Beutelsbach Castle (Ruin)

Beutelsbach Castle, also known as Kappelberg Castle Ruin, refers to the remains of a castle near the Beutelsbach district of the city of Weinstadt in the Rems-Murr district in Baden-Württemberg.
In 1968, the foundations and ruins of the spur castle were rediscovered and excavated during vineyard consolidation work on a mountain spur above Beutelsbach.
Today, the ruin is one of the most historically significant sites in the state. The castle was probably built in the 10th to 11th century by the Württembergers as their first ancestral castle.
