The Musée de l'Orangerie is an art gallery of impressionist and post-impressionist paintings. Though most famous for being the permanent home for eight Water Lilies murals by Claude Monet, the museum also contains works by Paul Cézanne, Henri Matisse, Amedeo Modigliani, Pablo Picasso, Pierre-Auguste Renoir, Henri Rousseau, Alfred Sisley, Chaim Soutine, and Maurice Utrillo, among others.
the Orangerie was originally built in 1852 by the architect Firmin Bourgeois and completed by his successor, Ludovico Visconti, to shelter the orange trees of the garden of the Tuileries. Used by the Third Republic in the nineteenth century as deposit for goods, an examination room, and place of lodging for mobilized soldiers, it also served to house sporting, musical, and patriotic events. Additionally, it was a place to display exhibitions of industry, animals, plants, as well as rare displays of painting.
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.
