The Panthéon (French: [pɑ̃.te.ɔ̃] , from Ancient Greek πάνθειον (pántheion) '[temple] to all the gods') is a monument in the 5th arrondissement of Paris, France. It stands in the Latin Quarter (Quartier Latin), on the Montagne Sainte-Geneviève, in the centre of the Place du Panthéon, which was named after it. The edifice was built between 1758 and 1790, from designs by Jacques-Germain Soufflot, at the behest of King Louis XV; the king intended it as a church dedicated to Saint Genevieve, Paris's patron saint, whose relics were to be housed in the church. Neither Soufflot nor Louis XV lived to see the church completed.
By the time the construction was finished, the French Revolution had started; the National Constituent Assembly voted in 1791 to transform the Church of Saint Genevieve into a mausoleum for the remains of distinguished French citizens, modelled on the Pantheon in Rome which had been used in this way since the 17th century. The first panthéonisé was Honoré Gabriel Riqueti, comte de Mirabeau, although his remains were removed from the building a few years later. The Panthéon was twice restored to church usage in the course of the 19th century—although Soufflot's remains were transferred inside it in 1829—until the French Third Republic finally decreed the building's exclusive use as a mausoleum in 1881. The placement of Victor Hugo's remains in the crypt in 1885 was its first entombment in over 50 years.
