Petermännchen (English: "Little Peterman"; German: [ˈpeːtɐˌmɛnçən]) is a small good-natured household spirit who is said to live in the Schwerin Palace in Schwerin, Mecklenburg, Germany.
[1] The diminutive spirit, maybe only a few feet tall, is often described as carrying many keys, roaming through the vaults and tunnels underneath the castle, unlocking doors as he goes.
Petermännchen is also said to have woken soldiers who fell asleep on their night-watch in order to save them from being punished.
Petermännchen has been described as appearing in numerous forms over the years, sometimes as an old man with a white, flowing beard extended down to his waist.
On another occasions Petermännchen would have a cavalier look with a stylish moustache, wearing a waistcoat, riding boots with spurs and a feathered hat.
