The superb collection of art housed within the Reina Sofia Museum makes it one of Madrid’s most popular attractions. An adventure through the space can begin with a ride up the glass elevator, which provides views of the plaza and buildings below. The second floor houses works from the permanent collection in about 10 galleries, while the top floor displays works from artists of the 1980s, as well as those of international artists. Visitors can take a guided tour of the galleries or opt for skip-the-line or early-access tours to beat the crowds. A visit to this museum is often combined with the Prado Museum and Thyssen-Bornemisza Museum; the three make up Madrid’s “Golden Triangle of Art” and are within walking distance of each other.
