The Wabasha Street Caves were transformed into an underground nightclub in 1933 called the 'Castle'. Today, the event center offers historic cave tours and big band music every Thursday night. The cave's tours lead the public through interesting locations with knowledgable guides and strikingly realistic scenery and costumes. Swing night on Thursdays attracts older couples looking for some good-old fun. The Wabasha Street Caves are the perfect blend of history for your company party, wedding, class reunion, etc.
