Meissen Cathedral The Meissen Cathedral or Church of St John and St Donatus (German: "Meißner Dom" ) is a Gothic church in Meissen in Saxony. It is situated on the castle hill of Meissen, adjacent to the Albrechtsburg castle. It was the episcopal see of the Bishopric of Meissen established by Emperor Otto I in 968. It replaced an older Romanesque church. The present-day hall church was built between 1260 and 1410, the interior features Gothic sculptures of founder Emperor Otto and his wife Adelaide of Italy as well as paintings from the studio of Lucas Cranach the Elder. The first Saxon elector from the House of Wettin, Margrave Frederick I, had the Prince's Chapel erected in 1425 as the burial place of his dynasty. The twin steeples were not attached until 1909.
