Palacio de Liria

While it's now the Madrid residence for the Dukes of Alba, it's not hard to notice the Palacio de Liria doesn't bear their name. Originally, the palace was built for the Third Duke of Liria in the late 18th century, but since passing hands to the Albas, it's lost none of its original glory.
The palace is now open to the public, where you can tour 14 rooms, admire one of the world's finest private art collections; with work by Goya and Rubens; and learn more about the palace's past with an immersive audio guide.
