Burgruine Landskron
During the Oppenheim Festival, from the end of August till the end of September, concerts are held at St. Catherine's, and open-air theater takes place in the Burgruine Landskron, the 12th-century imperial fortress ruins. From here, there's a wonderful view of the town and the vineyards, extending all the way to Mannheim and Frankfurt on a clear day. The castle ruins are northwest of the church. Follow Dalbergerstrasse north; from there it's a short, steep walk up to the ruins. For tickets to the open-air theater performances contact the Oppenheim tourist office.
