Panthéon was originally built as a church dedicated to St. Genevieve, but after many changes now combines liturgical functions with its role as a famous burial place. It is an early example of Neoclassicism, with afacade modelled after the Pantheon in Rome surmounted by a dome that owes some of its character to Bramante's 'Tempietto'. Among those buried in its necropolis are Voltaire, Rousseau, Victor Hugo, Émile Zola, Jean Moulin, Louis Braille, Jean Jaurès and Soufflot, its architect. Marie Curie is the only woman interred based on her own merits.
King Louis XV vowed in 1744 that if he recovered from an illness he would replace the ruined church of Sainte-Geneviève with an edifice worthy of the patron saint of Paris. The Marquis of Marigny was entrusted with the work. He had sponsored the architect Soufflot, whom he chose for the construction of the new Église Sainte-Geneviève, a major work in the neoclassical style. The overall design was that of a Greek cross with massive portico of Corinthian columns. Its ambitious lines called for a vast building 110 meters long by 84 meters wide, and 83 meters high. No less vast was its crypt.
The foundations were laid in 1758, but due to financial difficulties, it was only completed after Soufflot's death, by his pupil Jean-Baptiste Rondelet, in 1789. As it was completed at the start of the French Revolution, the new Revolutionary government ordered it to be changed from a church to a mausoleum for the interment of great Frenchmen, with a pediment of The Fatherland crowning the heroic and civic virtues by Jean Guillaume Moitte (replaced on the Bourbon Restoration with one by David d'Angers).
Twice since then it has reverted to being a church, only to become again a temple to the great intellectuals of France. In 1851, physicist Léon Foucault demonstrated the rotation of the Earth by his experiment conducted in the Panthéon, by constructing a 67 meter Foucault pendulum beneath the central dome. The original iron sphere from the pendulum was returned to the Panthéon in 1946 from the Conservatoire National des Arts et Métiers. From 1906 to 1922 this was the site of the famous sculpture The Thinker.References:
The Church of the Savior on Spilled Blood is one of the main sights of St. Petersburg. The church was built on the site where Tsar Alexander II was assassinated and was dedicated in his memory. Construction began in 1883 under Alexander III, as a memorial to his father, Alexander II. Work progressed slowly and was finally completed during the reign of Nicholas II in 1907. Funding was provided by the Imperial family with the support of many private donors.
Architecturally, the Cathedral differs from St. Petersburg's other structures. The city's architecture is predominantly Baroque and Neoclassical, but the Savior on Blood harks back to medieval Russian architecture in the spirit of romantic nationalism. It intentionally resembles the 17th-century Yaroslavl churches and the celebrated St. Basil's Cathedral in Moscow.
The Church contains over 7500 square metres of mosaics — according to its restorers, more than any other church in the world. The interior was designed by some of the most celebrated Russian artists of the day — including Viktor Vasnetsov, Mikhail Nesterov and Mikhail Vrubel — but the church's chief architect, Alfred Alexandrovich Parland, was relatively little-known (born in St. Petersburg in 1842 in a Baltic-German Lutheran family). Perhaps not surprisingly, the Church's construction ran well over budget, having been estimated at 3.6 million roubles but ending up costing over 4.6 million. The walls and ceilings inside the Church are completely covered in intricately detailed mosaics — the main pictures being biblical scenes or figures — but with very fine patterned borders setting off each picture.
In the aftermath of the Russian Revolution, the church was ransacked and looted, badly damaging its interior. The Soviet government closed the church in the early 1930s. During the Second World War when many people were starving due to the Siege of Leningrad by Nazi German military forces, the church was used as a temporary morgue for those who died in combat and from starvation and illness. The church suffered significant damage. After the war, it was used as a warehouse for vegetables, leading to the sardonic name of Saviour on Potatoes.
In July 1970, management of the Church passed to Saint Isaac's Cathedral (then used as a highly profitable museum) and proceeds from the Cathedral were funneled back into restoring the Church. It was reopened in August 1997, after 27 years of restoration, but has not been reconsecrated and does not function as a full-time place of worship; it is a Museum of Mosaics. Even before the Revolution it never functioned as a public place of worship; having been dedicated exclusively to the memory of the assassinated tsar, the only services were panikhidas (memorial services). The Church is now one of the main tourist attractions in St. Petersburg.
