Drachenfels
The Drachenfels is a prominent hill rising to 216 metres above the Rhine River, located near the town of Königswinter in the state of North Rhine‑Westphalia, Germany. The hill is best known for the ruins of the Drachenfels Castle, which originally dates back to the early Middle Ages but was largely rebuilt in the 13th and 14th centuries as a seat of the regional House of Nassau.

The surrounding area is part of the Rhine Gorge UNESCO World Heritage Site and is a center
