Not only is it one of the largest museums in Spain, it is also one of the country's most significant art libraries.
A visit here is essential for any and all travelers in Spain. Built as a museum in the late 18th century, the Prado is housed in the neoclassical Villanueva building where the Roman-inspired architecture allows for wide, light-infused domed galleries.
Masterpieces on view here include some of the most breathtaking examples of Spanish and European painters spanning the 12th to the 19th centuries, such as Velasquez, Goya, El Greco, Raphael, Rubens and Rembrandt, to name just a few. If time permits, visit the adjacent botanical gardens. Here visitors can contemplate an extensive, clearly-labeled arboretum.
