Eltz Castle is a medieval castle nestled in the hills above the Moselle between Koblenz and Trier, Germany. It is still owned by a branch of House of Eltz who have lived there since the 12th century.

Nestled in the hills above the Moselle River in Germany, Burg Eltz is a rare medieval marvel that has remained in the possession of the same family for over 850 years (33 generations). Built in the 12th century, it is a Ganerbenburg, meaning it was co-owned by different branches of the Eltz family who pooled resources to build separate living quarters within the same defensive walls. A supportive peer "history" highlight: it is one of the few Rhenish castles never destroyed by war. It survived the 17th-century Palatinate War of Succession because its lord was a high-ranking officer in the French army, who convinced his superiors to spare his home. Today, in 2026, it remains a "time capsule" of late-Gothic architecture, featuring eight towers reaching 35 meters and original furnishings that have never left the premises.
