Eltz Castle is a medieval castle nestled in the hills above the Moselle River between Koblenz and Trier, Germany. It is still owned by a branch of the same family that lived there in the 12th century, 33 generations ago. The Rubenach and Rodendorf families' homes in the castle are open to the public, while the Kempenich branch of the family uses the other third of the castle.

The castle is surrounded on three sides by the Elzbach River, a tributary on the north side of the Moselle. It is situated on a 70 m rock spur, on an important Roman trade route between rich farmlands and their markets. Sources
