Museum of Devils

Žmuidzinavičius Museum, also known as the Devil Museum, is a museum in Kaunas, Lithuania, dedicated to collecting and exhibiting sculptures and carvings of devils from all over the world. The collection was started by artist Antanas Žmuidzinavičius, and a memorial museum was established in his house after his death. In 1966, the devil collection consisted of 260 sculptures but visitors began to leave their own devils as gifts to the museum.
