With its Rapunzel towers and Romeo-and-Juliet balcony, Schloss Moyland is an unexpected sight amid the dull expanses of the Lower Rhine flatlands. The 'medieval' fairy-tale looks are deceiving: they're a 19th-century creation. Today, the castle houses a private modern-art collection that includes a huge assortment of works by Joseph Beuys. The labyrinthine interior is smothered in drawings, paintings and etchings. For a breather, take a spin around the lovely park with its old trees and wacky sculptures.
