Fodor's Expert Review Klosterruine Limburg

Overlooking the suburb of Grethen are the ruins of Kloster Limburg. Emperor Konrad II laid the cornerstone in 1030, supposedly on the same day that he laid the cornerstone of the Kaiserdom in Speyer. The monastery was never completely rebuilt after a fire in 1504, but it's a majestic backdrop for open-air performances in the summer months.
