Castrovalva 1930

"Castrovalva" (1930), a lithograph by M.C. Escher, depicts a seemingly impossible village perched precariously on a cliff. The perspective is distorted, playing with our sense of depth and gravity. Buildings on the cliff appear to defy logic as they appear to be suspended in mid-air or even growing out of the cliff itself. Escher's signature use of impossible spaces and optical illusions makes this artwork a prime example of his signature style.
