Fodor's Expert Review Philippsburg Castle

This historic 16th-century castle, whose courtyard is paved with stones from the Rhine, was built in 156871 as nobleman's estate and later to house the widow of Philipp II, it's first owner. A wine cellar in the inner courtyard is still in use. Opposite the cellar you'll find a charming renaissance garden, restored to the original 1607 plans. The castle now houses the European Castles Institute, whose notable library contains over 25,000 volumes about every known castle in Europe, which can be visited by appointment.
