The Théâtre du Châtelet () is a theatre and opera house, located in the place du Châtelet in the 1st arrondissement of Paris, France. One of two theatres (the other being the Théâtre de la Ville) built on the site of a châtelet, a small castle or fortress, it was designed by Gabriel Davioud at the request of Baron Haussmann between 1860 and 1862. Originally named the Théâtre Impérial du Châtelet, it has undergone remodeling and name changes over the years. Currently it seats 2,500 people. Description The theatre is one of two apparent twins constructed along the quays of the Seine, facing each other across the open Place du Châtelet. The other is the Théâtre de la Ville. Their external architecture is essentially Palladian entrances under arcades, although their interior layouts differ considerably. At the centre of the plaza is an ornate, sphinx-endowed fountain, erected in 1808, which commemorates Napoleon's victory in Egypt. Origins The Théâtre Impérial du Châtelet was built for Hippolyte Hostein's equestrian company, the Théâtre Impérial du Cirque, whose previous theatre, the Cirque Olympique on the Boulevard du Temple, was slated for demolition by Baron Haussmann to allow the construction of the Boulevard du Prince-Eugène (now the Boulevard Voltaire). The site for the new theatre was acquired by the City of Paris in October 1859, and construction took place between 1860 and 1862. The interior designers included Eugène Carrières and Armand Cambon, and the curtain was created by Charles Cambon. The theatre originally seated 2,200 people, although Haussmann claimed it held 3,600. The repertory, fixed by a decree of 20 September 1862, included military works and féeries in one or several acts, as well as dramas and vaudevilles. Hostein left as director in September 1868. Nestor Roqueplan ran the theatre from 1 July 1869 to April 1870. Fall of the Second Empire The theatre was closed from September 1870 to July 1871 due to the Franco-Prussian War. The war brought about the fall of the Second French Empire, and under the succeeding French Third Republic, the appellation impérial was dropped. Hippolyte Hostein returned as the theatre's director in 1873–1874. Notably, beginning in April 1876, the stage version of Jules Verne's Around the World in Eighty Days, adapted by Verne and Adolphe d'Ennery, began a run spanning sixty-four years and 2,195 performances (although not continuously). It was only the Nazi occupation of Paris in May 1940 that
