However, the period between 1042 and 1174, during which Emperor Frederick I "Barbarossa" stayed there, it is not mentioned in documents at all. In 1194, his son, Henry VI made peace with his former enemy Heinrich der Lowe (Henry the Lion) at Tilleda. This is the last time a king is documented to have been there.
