Escher at the Palace is dedicated to the work of Hollands most famous graphic artist M.C. Escher. Nearly all his prints are exhibited, among them Belvedere, Drawing Hands, Waterfall and Ascending and Descending. Here you can see how Escher changed fishes into birds, made water flow upstream and his less known, but very attractive early Italian landscapes. On our main- and first floor you can see how his work progressed from depicting the real world to his constructed worlds. Optical illusion is a key word in his work.An optical illusion depicts something which is in fact impossible. M.C. Escher was a master in this field. An optical illusion literally means doing puzzles with your eyes. The visitor will be able to unravel some of Eschers mysteries like the Impossible Penrose Triangle by constructing one himself. The extra presentation In the Eye of Escher shows various themes in which Escher was involved, like reflection, perception and perspective.
