Klopp Castle

In the nineteenth century, the bergfried (similar to a keep) from the original medieval fortified castle was restored and a new building added which houses the town's administration.

The castle stands on a hill above the town with a wide-ranging view, which may have been the site of a Roman fortification built by Nero Claudius Drusus at Bingium around 10 CE.

Together with Ehrenfels Castle on the opposite side of the Rhine and later the Mouse Tower, it enabled the Archbishopric of Mainz to exact tolls on river trade.

Both charged tourists to climb the gate tower as a viewing platform;[9] Faber built a stairway up the outside of the walls and a viewing room at the top which he furnished with books of poetry, a comfortable sofa and a fully equipped writing desk, and laid out the grounds as a garden with romantic paths through the grapevines, trees and flowers.

[9][3][14] The base of the bergfried, the moat and parts of the southern curtain wall and its chemin de ronde are the only remnants of the medieval castle.
