The Smithsonian American Art Museum has one of the world's largest and most inclusive collections of art, from the colonial period to the present, made in the United States. The museum has more than 7,000 artists represented in the collection, which contains the largest collection of New Deal art; a collection of contemporary craft, American impressionist paintings, and masterpieces from the Gilded Age; photography, modern folk art, works by African American and Latino artists, images of western expansion, and realist art from the first half of the twentieth century. Most exhibitions take place in the museum's main building, the old Patent Office Building (shared with the National Portrait Gallery), while craft-focused exhibitions are shown in the museum's Renwick Gallery.
The main building, the Old Patent Office Building, is a National Historic Landmark and is considered an example of Greek Revival architecture in the United States. It was designed by architects Robert Mills and Thomas U. Walter.
Part of the Smithsonian Institution, the museum has a broad variety of American art, with more than 7,000 artists represented, that covers all regions and art movements found in the United States. Among the significant artists represented in its collection are Nam June Paik, Jenny Holzer, David Hockney, Georgia O'Keeffe, John Singer Sargent, Albert Pinkham Ryder, Albert Bierstadt, Edmonia Lewis, Thomas Moran, James Gill, Edward Hopper, John William 'Uncle Jack' Dey, Karen LaMonte and Winslow Homer.References:
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.
