History+
Gleichen Castle was likely built in the 12th century as an imperial castle during the Staufer administrative reforms. Its first documented mention was in 1294, when it was owned by the Lords of Gleichen, who are considered its probable builders. After the family died out or moved away, the complex passed to the Lords of Limpurg. Between 1298 and 1308, Gleichen came into the possession of the Lords of Löwenstein under King Albrecht I. Another mention appears in a 1332 document by Emperor Ludwig. The castle subsequently changed hands multiple times until it fell to the House of Hohenlohe-Bartenstein in 1416, which owned the complex until its decay.
