The Musée d'Orsay was built between 1898 and 1900. The museum holds mainly French art dating from 1848 to 1915, including paintings, sculptures, furniture, and photography. It houses the largest collection of impressionist and post-impressionist masterpieces in the world, by painters including Monet, Manet, Degas, Renoir, Cézanne, Seurat, Sisley, Gauguin and Van Gogh. Many of these works were held at the Galerie nationale du Jeu de Paume prior to the museum's opening in 1986.
The museum building was originally a railway station, Gare d'Orsay, constructed for the Chemin de Fer de Paris à Orléans and finished in time for the 1900 Exposition Universelle to the design of three architects: Lucien Magne, Émile Bénard and Victor Laloux. It was the terminus for the railways of southwestern France until 1939.
By 1939 the station's short platforms had become unsuitable for the longer trains that had come to be used for mainline services. After 1939 it was used for suburban services and part of it became a mailing centre during World War II. It was then used as a set for several films, such as Kafka's The Trial adapted by Orson Welles, and as a haven for the Renaud–Barrault Theatre Company and for auctioneers, while the Hôtel Drouot was being rebuilt.
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
