Named for its distinctive color Casa Rosada is the seat of the national government and houses the office of the President. It is closed to the public. It was from the balcony here, at the presidential palace, that Eva Perón famously addressed the throngs of impassioned supporters packed into Plaza de Mayo. The building occupies the site where colonial riverbank fortifications once stood; today, however, after repeated landfills, Casa Rosada stands more than 1km inland.
Located behind the palace is the interesting Museo Casa Rosada (casarosada.gob.ar; free; 11:00am-6:00pm Wed-Sun) which covers over 200 years of Argentina's history. More than 10,000 historical pieces are exhibited, such as furniture and paintings, the great Cadillac of Juan Domingo Perón, and personal objects of the people who led the destinies of this country.
Perhaps the most beautiful object in the museum is the mural Ejercicio Plástico (Plastic Exercise) created in 1933 by a team formed of the famous Mexican muralist David Alfaro Siqueiros and the Argentinean painters Lino Enea Spilimbergo, Antonio Berni and Juan Carlos Castagnino, together with the Uruguayan set designer Enrique Lázaro. Guided tours, lasting 45 minutes, take place on Fridays, Saturdays and Sundays at 4pm.
