The Eiffel Tower. Key Facts in Short

One of the most important symbols in Europe. I would even say it’s the most famous one. The Eiffel Tower is visited by 7 million people every year.

The Eiffel Tower was built for the 1889 Exposition Universelle in Paris. Gustave Eiffel, an expert in metal construction, designed and oversaw the project, and the tower was named after him.

Although initially intended to stand for only twenty years, we are soon approaching its 130th birthday. The construction of the Eiffel Tower took a total of 2 years, 2 months, and 5 days.

The Eiffel Tower stands at a height of 324 meters and features three floors that offer breathtaking views. The highest floor, located near the top, is situated at 276 meters. From the third floor, visitors can capture panoramic shots of the surrounding scenery. This floor consists of two levels: a fully sheltered lower level and an upper level that is open but secured with a net. The first floor of the Eiffel Tower is expansive in size and offers various attractions. During the winter season, an ice skating rink is constructed at one of its corners, adding a delightful activity for visitors to enjoy. The second floor, positioned at a height of 115 meters, provides an excellent vantage point for capturing photos of the intricate metal structures of the tower. It offers the opportunity to explore at least two levels, allowing visitors to freely move around and explore the area.

You can use elevators to reach all floors, but you need to decide where you want to go before getting a ticket. You can skip the first floor and take an elevator directly to the second floor of the Eiffel Tower. Once you’re on the second floor, you can either end your visit or take another elevator to the top level. When coming down from the top level, you must use the elevator. However, on the second floor, you can choose to take the elevator or use the stairs to go back to the ground level. During my last visit to the Eiffel Tower, I chose to take the stairs from the second floor to the ground. It was a bit of a workout to go down more than 100 meters, but it was worth it because you can see the metal structure up close.

The tower’s framework is composed of iron, which was a revolutionary material in the late 19th century. Around 18,000 individual iron pieces and over 2.5 million rivets were used to assemble the tower. Gustave Eiffel and his team paid careful attention to wind resistance during the tower’s design and construction. The open lattice structure and strategic placement of supports contribute to the tower’s stability in windy conditions. The Eiffel Tower features a unique arch design, which provides both strength and aesthetic appeal. The arches intersect at the tower’s second level, creating a visually captivating pattern. The tower originally had hydraulic elevators that were later replaced with electric elevators. These elevators, equipped with modern safety features, efficiently transport visitors to different levels of the tower. Diagonal bracing elements were incorporated into the tower’s design to enhance its structural integrity. These elements help distribute loads and reinforce the tower against external forces. The Eiffel Tower’s foundation consists of concrete footings, deep underground, to provide stability and support for the towering structure. The foundation was carefully engineered to withstand the immense weight of the tower. The weight of the Eiffel Tower is approximately 7,300 metric tons.

Gustave Eiffel is recognized as the architect and chief engineer behind the renowned Eiffel Tower. He was 55 years old when construction began on the Eiffel Tower in 1887. By the time Gustave Eiffel worked on the Eiffel Tower, he was already an established chief engineer and had his own design and construction company. Eiffel founded Gustave Eiffel & Cie in 1866, his own engineering firm, which specialized in metal construction. He had been involved in prominent projects, including designing railway bridges and the internal structure of the Statue of Liberty. His engineering firm was responsible for the design and construction of the Eiffel Tower, though the tower itself was initially conceived by two of his employees, Maurice Koechlin and Émile Nouguier, with Eiffel lending his full support and expertise to the project. During my travels, I came across his name also in Porto, Portugal, as he designed or co-designed two do the bridges spanning the Douro River.

Gustave Eiffel, born Alexandre Gustave Eiffel in 1832 in Dijon, France, was a renowned engineer and architect. There was no engineering tradition in his family; however, his mother ran a successful business, which allowed him to attend prestigious schools, including the Lycée Royal in Dijon and later the École Centrale des Arts et Manufactures in Paris, where he initially studied chemistry but eventually shifted his focus to engineering.

Eiffel specialized in metal construction, showcasing his talent and innovation in structural engineering. While the Eiffel Tower remains his most celebrated achievement, Gustave Eiffel’s influence extended far beyond it. His engineering brilliance and forward-thinking approach led him to undertake various noteworthy projects around the world. He left his mark on several other remarkable structures like the Statue of Liberty’s interior iron framework, the Garabit Viaduct in France, and the Porto Bridge in Portugal. These structures showcase his expertise in metal construction and innovative use of iron, blending engineering excellence with aesthetic appeal.

These projects, among many others, demonstrated Eiffel’s ability to push the boundaries of structural engineering and his penchant for combining functionality with artistic beauty. His meticulous attention to detail, understanding of wind resistance, and innovative use of iron revolutionized the field of construction. Beyond his architectural feats, Eiffel’s later career saw him establish the Société des Établissements Eiffel, a company focused on constructing bridges, railway stations, and other impressive metal structures around the world. His expertise and reputation allowed him to leave a lasting impact on the field of engineering, inspiring future generations of architects and engineers.

After Gustave Eiffel’s involvement in the construction of the Eiffel Tower and other significant projects, Société des Établissements Eiffel faced a major challenge in 1892. Eiffel became embroiled in a scandal related to the failed Panama Canal project, in which he had been contracted to design locks for the canal. The project faced financial difficulties and accusations of fraud, leading to legal investigations. Although Eiffel was initially convicted and sentenced to two years in prison and a fine, he was later fully exonerated by the French Supreme Court in 1893. However, the scandal had damaged his reputation, and it prompted Eiffel to step back from business. He retired from active management of his company around this time. Following his retirement, Société des Établissements Eiffel continued to operate under different leadership. The firm diversified and became involved in other engineering projects, but its activities were no longer tied to Eiffel himself. Over the years, the company underwent several transformations and mergers. Eventually, it became part of larger engineering groups.

The Eiffel Tower might be one of the most visited landmarks in the world, but it still offers something unique — whether it’s the view, the engineering, or simply the experience of standing beneath it. Even if you decide not to go up, seeing it from the ground is worth the stop.

The Eiffel Tower. Key Facts in Short

Notre Dame fire. A devastating moment to see

While inside, you might have thought it was eternal. And it is. But on Monday night it was a devastating moment to watch it burn. I heard the bad news of the Notre Dame fire around eight or nine in the evening. The spire was already collapsed and the fire quite extensive.

Today we live in the world, where news travels fast. The Notre Dame fire was of that importance that basically all major TV stations around Europe and in the US (I cannot say anything about the other continents) were broadcasting live pictures till very late night hours. Changing channels you were able to observe the rescue efforts. They were extensive and made a modern way.

Another communique was, much of the treasures had been carried out of the building. They had been deposited in a safe place.

First I was thinking, how it was possible in the modern world that a fire like that appeared at all. I was sitting paralyzed in front of the TV set wondering whether I would be able to see the interior yet again in my lifetime. But later in the night and in the morning I was glad to see how professionally the rescue was carried out.

As I started to follow, the Notre Dame fire rescue efforts, the flames were already in the North belfry. The news was, it might collapse as well. Temperature changes might have caused changes in the stone and in the binding material. Unbelievable. But shortly after a communique – the fire in the belfry was contained. Soon after, you could have seen red and white lights pointing into its interior. One of the broadcasting stations made a close-up. At that moment, I realized, there were firefighters inside, who scanned the belfry with a night vision device, probably equipped with a temperature detector as well. The other doused indicated spots with a stream of water to cool the stone construction slowly down. You could also have seen firefighters on ladders quite close to the top of the cathedral dousing its interior with water at several points.

The next morning, the firefighters published first photos and films of the interior. It was quite a relief. If candles were still burning in the back of the cathedral and many candles around the altar seemed to be untouched, it was clear the temperatures down inside were not as high as expected. Robots doused streams of water on the hot debris on the floor. The action was to contain the fire but also to cool the air down. If candles were intact, the stained glass windows were probably intact as well as paintings that were not possible to be removed under fire. Most of the damage would be because of the roof debris that had fallen down and of water used in action.

It seems still impossible to avoid fires in the very old buildings today. Yet the modern equipment and technology allow containing fires in a way that would be impossible even ten or twenty years ago.

The reconstruction will also not last for years as it used to be in the past. If you travel to Europe, visit the cathedrals, often you are told how difficult it was to rebuild a cathedral after a fire or warfare. Today, at least in the case of Notre Dame funding seems not to be a problem. Already hundreds of millions of Euros had been raised or declared. The main stone structure of the cathedral will be scanned and put into the mathematical models. Computers will do the math. This will not be trial and error as it used to be done in the past. To reconstruct the roof for sure modern materials will be used as we know already the oak beams replacement is not possible. Oakwood is rare, takes much time to grow, and the grown-up trees are mostly under protection. The reconstruction of the ceiling will arise some problems, for it will have to be reconstructed using the original technology. I wonder only what technique and materials will be used to rebuild the spire. Will it be the exact reflection of the old one or will it get some modern architectural touch? The bottleneck will be the expert labor. Specialists able to reconstruct pieces of art will probably have to come from all over Europe or even other continents. They will have to remove the damage caused by fire and water, as well as mechanical damage. Many working hours will be needed to remove smoke black from the stone facade outside and inside the cathedral. The laser technique will be used. It is precise but takes many but many working hours.

I have my doubts, whether the five-year timeline will be kept as the French President declares. Still, I think less than ten years will be needed to do the work. The Notre Dame will be rebuilt, and the interior reconstructed as it used to be many times before. It is hoped that most of us will be able to visit it yet again in the lifetime.

But today and for years to come, hopefully only a couple of years, this is just memories.

The Panthéon of Paris

The Panthéon in Paris — not to be confused with its Roman counterpart — is a must-see landmark in the French capital. Unlike many of the city’s historic monuments, it is relatively recent, completed in the late 18th century. It stands atop Montagne Sainte-Geneviève, a hill that once formed the heart of Roman Lutetia, home to the ancient Forum. The site held religious significance long before the Christian era, making it a fitting location for what would become both a church and, later, a civic temple.

Originally, the Panthéon in Paris was conceived as a church dedicated to Saint Geneviève, the patron saint of Paris. It was commissioned by King Louis XV, the great-grandson of Louis XIV, as a votive offering in gratitude for his recovery from a serious illness. This grand new structure was intended to replace the deteriorating medieval church that had long stood on the same site. The design was entrusted to Jacques-Germain Soufflot, one of the leading French architects of the 18th century, whose work on the project began in 1758. Soufflot aimed to create a monumental neoclassical structure that would reflect the rational ideals of the Enlightenment, combining architectural purity with engineering ambition. Drawing inspiration from ancient Roman and Greek forms, his design is characterised by symmetrical proportions, a cruciform layout, and a majestic façade adorned with Corinthian columns. These elements create a striking sense of balance and gravitas, drawing the visitor’s gaze upward. Yet the project was not purely religious or aesthetic; it also carried a political message. At a time when the monarchy’s image was weakening, Louis XV used the gesture as a way to reconnect with his people and reassert his authority through an act of public piety wrapped in architectural grandeur.

The construction of the Panthéon lasted from 1764 to 1789, concluding just as the French Revolution began to unfold. Remarkably, the building was completed only months before the storming of the Bastille, a moment that came to symbolise the collapse of the Ancien Régime. Although originally conceived as a place of worship, the Panthéon was almost immediately reclaimed by revolutionary ideals. In line with the Revolution’s emphasis on secularism and civic virtue, the National Constituent Assembly voted in 1791 to transform the newly built church into a temple of the nation, intended to honour the great men of the era of French liberty. Among the first to be interred were Voltaire and Rousseau, figures who had helped shape the very ideals the Revolution sought to realise. Under Napoleon, the Panthéon briefly regained its religious function, only to revert once more to a civic role. Over the following decades, it oscillated between sacred and secular status no fewer than five times, reflecting France’s own turbulent shifts between monarchy, empire and republic. It was not until 1885, with the state funeral of Victor Hugo, that its secular identity was firmly established — and has remained so ever since.

Although the building had begun serving as the Panthéon from this point onwards, its secular status was not consistently maintained. Until 1885, in line with the political fluctuations between Republic and Empire, it was twice reconsecrated as a church. Architecturally, however, the Panthéon has always retained the character of a religious structure: it follows a cruciform floor plan, and its distinctive triple-dome system — an engineering marvel of its time — was inspired by St Peter’s Basilica in Rome. The outer dome, visible from across the city, conceals two interior shells that provide structural support for its immense weight. Inside, a number of impressive frescoes depicting scenes from the life of Saint Geneviève remain remarkably well preserved, a reminder of the building’s original dedication.

Today, however, the Panthéon functions as an entirely secular space. Its interior also features sculptural works that honour the French Revolution and its ideals, reinforcing the building’s civic purpose. Beneath the main structure lies the crypt, which serves as the burial site for many of France’s most celebrated figures. The crypt itself is austere in design: most tombs are housed in simple stone chambers, often containing up to five individuals. Only a select few have been specially decorated or given prominent positions, reflecting the scale of their national recognition.

Below some photo impressions of this impressive building and its interiors.

One of the most striking architectural features of the Panthéon in Paris is its massive dome, inspired by the Pantheon in Rome. It dominates the skyline and is clearly visible both from the exterior and within the building. The dome is supported by a colonnaded portico featuring elegant Corinthian columns — a hallmark of neoclassical design. Above the portico sits a triangular pediment, richly decorated with sculptural reliefs that depict key moments from French history. At its centre stands an allegorical figure representing France herself, flanked by great Enlightenment thinkers such as Voltaire and Rousseau. Just above, the inscription reads: Aux grands hommes la patrie reconnaissante (To the great men, the grateful homeland) — a message both revolutionary and patriotic. The use of sculptural pediments to convey political or historical meaning was a common feature of neoclassical public architecture, linking the Panthéon to a broader European tradition of monumental symbolism. From its completion in the late 18th century until the Eiffel Tower (1889), the Panthéon remained the tallest building in Paris, its dome dominating the skyline.

The interior of the Panthéon is no less impressive than its exterior, combining neoclassical design principles with layers of historical and cultural significance. Its floor plan follows a cruciform layout, with the central dome positioned at the intersection of the cross-shaped structure. An oculus at the top of the dome allows natural light to filter into the space, creating a dramatic play of shadow and illumination beneath. It was beneath this dome in 1851 that Léon Foucault demonstrated the Earth’s rotation with his celebrated pendulum; a replica of the Foucault pendulum can still be seen today. This architectural arrangement is characteristic of many neoclassical churches and civic buildings, drawing on ancient Roman models reinterpreted through Enlightenment ideals.

The interior is richly adorned with murals and sculptures, many of which reflect the shifting identity of the Panthéon over time. As the building evolved from a religious space to a secular mausoleum, its artistic programme also changed. The subjects depicted came to reflect the values of the French Republic, celebrating national unity, civic virtue and historical memory, rather than purely religious devotion.

As you enter and look straight ahead — towards the place where an altar would traditionally stand — you are instead met with a monumental tribute to the National Convention, the revolutionary assembly first elected in 1792 through universal male suffrage, regardless of class. This bold positioning makes a clear and deliberate statement: the ideals of the Republic have replaced those of the Church. The monument is flanked by allegorical figures of Liberty and the Republic, reinforcing its civic symbolism.

Behind the ensemble is a dramatic fresco entitled Towards Glory, which depicts scenes from the Napoleonic Wars — a reminder of the turbulent period that followed the transformation of the First French Republic into the French Empire under Napoleon Bonaparte.

The Panthéon in Paris serves as the final resting place for numerous notable figures from French history, whose interment within its walls reflects the nation’s recognition of their lasting contributions across politics, science, literature, and philosophy. The crypt below the main structure is arranged with deliberate simplicity, echoing the Revolutionary ideal of equality in death — a powerful contrast to the often elaborate tombs of monarchs and clergy elsewhere.

Among those honoured are:

Voltaire (1694–1778) – The celebrated Enlightenment writer and philosopher, born François-Marie Arouet, was one of the first individuals to be interred in the Panthéon, in 1791. His sharp wit and fearless criticism of religious dogma, intolerance, and absolutism had a profound impact on the intellectual climate of 18th-century Europe.

Jean-Jacques Rousseau (1712–1778) – Another key figure of the Enlightenment, Rousseau is best known for his influential writings on political philosophy, education, and human nature. His belief in the general will and the natural goodness of man helped shape modern concepts of democracy and social contract theory. His remains were transferred to the Panthéon in 1794, just two years after Voltaire’s, symbolically reuniting two intellectual rivals at the heart of the Republic.

Victor Hugo (1802–1885) – The celebrated French writer, poet and playwright, Hugo is best known for his literary masterpieces Les Misérables and The Hunchback of Notre-Dame. A towering figure in French Romanticism and a vocal advocate for social justice and republican ideals, he was given a state funeral attended by over two million people. His burial in the Panthéon in 1885 marked a turning point, firmly establishing the building’s role as a secular monument to national memory.

Émile Zola (1840–1902) – A prominent novelist and playwright, Zola is best known for his powerful works of naturalist fiction, including Germinal and Nana, which exposed the harsh realities of working-class life in 19th-century France. His writing frequently engaged with social injustice, political corruption and human suffering, making him one of the most influential public voices of his time. He was interred in the Panthéon in 1908, in recognition not only of his literary achievements but also his courage during the Dreyfus Affair, where he famously defended truth over nationalism.

Marie Curie (1867–1934) – A pioneering physicist and chemist, Curie is renowned for her groundbreaking research on radioactivity, for which she was awarded two Nobel Prizes – in Physics and in Chemistry – the first person ever to achieve this distinction. In 1995, she became the first woman to be interred in the Panthéon on her own merits, a historic recognition of both her scientific achievements and her enduring legacy in a field long dominated by men.

Louis Braille (1809–1852) – The inventor of the Braille system, which revolutionised written communication for the blind and visually impaired. Blinded as a child, Braille developed his tactile reading and writing system while still a teenager, and it would go on to transform access to education and literacy worldwide. His remains were transferred to the Panthéon in 1952, marking the centenary of his death and honouring his profound humanitarian contribution.

René Descartes (1596–1650) – Although he died over a century before the construction of the Panthéon, Descartes was posthumously honoured for his contributions to philosophy and mathematics when his remains were transferred there in 1819. Often regarded as the father of modern philosophy, he is best known for his statement Cogito, ergo sum (I think, therefore I am) and for laying the foundations of analytical geometry. However, some historians have questioned whether his remains are still housed in the Panthéon today, as they may have been lost or displaced during earlier reburials.

Alexandre Dumas (1802–1870) – The renowned novelist and playwright, Dumas is celebrated worldwide for his swashbuckling tales such as The Three Musketeers and The Count of Monte Cristo. His works, translated into dozens of languages, have shaped popular culture across the globe and remain among the most widely read of all French literature. His remains were transferred to the Panthéon in 2002, more than a century after his death, in recognition of his enduring literary legacy.

Joséphine Baker (1906–1975) – Born in the United States, Baker became an internationally acclaimed dancer, singer and actress, and later a heroine of the French Resistance during the Second World War. She was also a prominent civil rights activist, using her fame to challenge racial segregation and inequality. In 2021, she became the first Black woman to be interred in the Panthéon, honoured both for her cultural influence and her unwavering fight for freedom and equality.

Recent decades have seen new figures added — including Simone Veil (1927–2017), a Holocaust survivor and pioneering advocate of women’s rights — underscoring that the Panthéon is not a closed chapter but a living testament to the values France chooses to honour.

Today, the Panthéon stands as a living monument, one that continues to evolve with each new entombment. As France reflects on its identity and collective memory, debates persist over who should be accorded a place within this national shrine. In this sense, the Panthéon is not merely a static museum, but rather a mirror of French values and ideals across the centuries.
