Bolsa de Madrid
This densely tree-lined, wide and central avenue is a landmark for the city residents and the location of important cultural and tourist spots in the city, including the so-called "Golden Triangle of Art", which encompasses three museums: the Prado Museum (with highlights such as Diego Velázquez's "Las Meninas" and Francisco de Goya's "La maja vestida" and "La maja desnuda"), the Thyssen-Bornemisza Museum (housing a collection that spans eight centuries of European painting), and the Reina Sofia Museum (where Pablo Picasso's "Guernica" hangs, among a collection of 20th-century art). In the vicinity are located the Parque del Buen Retiro and the Casón del Buen Retiro (hosting the 19th-century collection of the Prado Museum), as well as the headquarters of the Real Academia Española (the Spanish language academy), the Bolsa de Madrid (the city's stock exchange), and the Congreso de los Diputados (the national congress).
