Burg Werdeck, Medieval castle ruin in Rot am See, Germany.

Burg Werdeck is the ruin of a spur castle on a 416 m high spur above a north loop of the Brettach, about one kilometre west-northwest of the Werdeck farmstead in Rot am See. It was probably a tower castle with a vaulted cellar, partly surrounded by a ring wall; the neck ditch and shield wall survive.

Werdeck Castle was first mentioned in 1220 and built in the 13th century on a spur 416 m above sea level over a northern loop of the Brettach. It belonged to the Counts of Lobenhausen and the Lords of Hohenlohe. By the 16th century it had fallen into ruin, and it was destroyed in 1797.

The name Werdeck comes from the hamlet of Werdeck below the site, itself part of Rot am See. The castle belonged to the Counts of Lobenhausen and the Lords of Hohenlohe, whose names are tied to the site's medieval tenure. Visitors today see the neck ditch and shield wall, the surviving parts of the fortification.

The ruins are accessible via forest paths starting from Rot am See and winding through the woodland. Sturdy footwear is recommended since the terrain is uneven and walking requires some care to navigate safely.

The name Werdeck likely comes from the site's position: the spur juts above a north loop of the Brettach, about a kilometre west-northwest of the Werdeck farmstead in Rot am See. Visitors can still trace the neck ditch cut across the ridge and the shield wall that guarded the approach.
