Museo Nacional de Arte (National Museum of Art)

Prado Museum (3.45 million). This museum in Madrid is one of the most important art galleries in the world, presenting works by Velázquez, Goya, Bosch, Rubens, and Titian. Its key pieces include Las Meninas, The Garden of Earthly Delights, and The Naked Maja.

This explains why the Prado has been described as a museum of painters rather than paintings, as the artists represented are usually represented in a superlative way, boasting the largest collections of works by Bosch, Titian, El Greco, Rubens, Velázquez and Goya, sometimes with more than a hundred works.

What is the biggest museum in Mexico? The National Museum of Anthropology is considered the biggest, most visited, and comprises the widest collection of objects. It is also the oldest museum in Mexico.

Located on Avenida del Libertador in Buenos Aires' Recoleta neighborhood, the museum offers free admission, and welcomes visitors Tuesday through Friday from 11 a.m. to 8 p.m. and on weekends from 10 a.m. to 8 p.m. The museum is closed on Mondays.
