Liebenstein Castle

About

Liebenstein Castle (German: Burg Liebenstein) is a castle in Liebenstein in the Ilm-Kreis, Thuringia, Germany. It was originally built in the 12th century by the counts of Käfernburg; the castellans were the counts' ministeriales, the lords of Liebenstein. The castle was extensively reconstructed in the 16th century, and subsequently used as a quarry for building-stone.
