Warenburg Castle (Ruin)

The Warenburg ruin, also known as Wartenberg, is a castle ruin on the current outskirts of the city of Villingen-Schwenningen in the Schwarzwald-Baar district in Baden-Württemberg.

The castle, presumably built in the 11th century, was owned by the Zähringer and Austria. It was first documented in 1320 and formed its own dominion with the neighboring villages of Marbach, Rietheim, Klengen, Überauchen, and Grüningen. In 1472, the city of Villingen acquired the complex and razed it. The Meierhof continued to exist until the Thirty Years' War and was also destroyed in 1633 to prevent it from serving as a refuge for the advancing Swedes. Wall remains and foundation remains of a keep are still preserved from the former castle complex. The castle plateau, surrounded by a moat, possibly had a larger outer bailey.
