Madrid is home to the prestigious National Library (Biblioteca Nacional) and the Library of the Royal Palace, which has a recognized historic collection. Madrid has a long literary tradition. Each year, thousands of people attend the Madrid Feria del Libro (book fair), one of many events that continue to thrive in the city's lively literary scene. The city is also well known for its used bookshops.
Some of the world's most important museums are in Madrid. Foremost among these is the Prado Museum, which opened in 1819. The museum's thousands of paintings were collected by the Spanish monarchy and the Catholic Church over several centuries. About 1,500 paintings can be shown at a time. Some of Spain's most renowned painters are represented at the Prado, including Velázquez, Goya, El Greco, Zurbarán, Ribera, and Murillo, and many other Europeans, like Rembrandt, Rubens, Botticelli, Rafael, and Tintoretto.
Picasso's Guernica, which had been housed in New York City, is now at the Reina Sofía museum, home of Spain's modern art. Works by Miró, Oteiza, and Julio González are part of the permanent collection.
