This is one of the most important museums in the world. They let me perform a freestyle rap in the museum inspired by one of the exhibits; it was unforgettable. Also, Bosch's “Garden of Earthly Delights” is here. It’s so impressive and inspiring to see in person. Make sure you check out this spot!

Quite simply the most important art museum in Spain. Go for the huge concentration of masterpieces, among them Spanish Romanesque murals, Gothic altarpieces, Renaissance sculptures and the world’s greatest collection of works by Hieronymus Bosch – plus plenty of El Greco, and Dürer’s extraordinary 1498 ‘Self-Portrait’. Don’t miss the Velázquez Rooms, featuring the artist’s massive state portraits of Felipe IV and his court, with pride of place taken by the timeless ‘Las Meninas’.
