Sirgenstein Castle
Sirgenstein Castle is a ruined castle on rock, over twenty metres high, with a cave inhabited in the Stone Age, the Sirgenstein, between the town of Blaubeuren and hamlet of Schelklingen in Alb-Donau-Kreis in Baden-Württemberg.
The rock castle was probably built in the 13th century. Today its visible remains include castle walls, rusticated ashlar blocks and a neck ditch.Literature
