Fodor's Expert Review Marksburg

On the eastern shore overlooking the town of Braubach is the Marksburg. Built in the 13th century to protect the silver and lead mines in the area, it's the only land-based castle on the Rhine to have survived the centuries intact. Within its massive walls are a collection of weapons and manuscripts, a medieval botanical garden, and a self-service restaurant with a terrace offering stunning views. The castle can only be visited as part of a 50-minute guided tour: individual English tours take place daily during the summer months at 1 pm and 4 pm; call ahead if you'd like to join a pre-arranged tour at a different time.
