Burg Waseneck, Castle ruin in Oberndorf am Neckar, Germany

Burg Waseneck is a medieval castle ruin in Oberndorf am Neckar situated on a hilltop overlooking the river valley. The site preserves remains of the main tower, courtyard walls, and the fortification's defensive structures.

The Dukes of Teck built the castle around 1220 and expanded it in 1270. The Maier von Waseneck served as administrators and castle men until 1363, when Duke Friedrich of Teck inherited it. After passing through several owners, it came to Count Eberhard IV of Württemberg in 1416 and was already described as a ruin in 1460. In 1806 it became state property of the Kingdom of Württemberg, and from 1968 to 1980 its foundations were uncovered, restored and partly rebuilt.

The name Waseneck is first documented through the Maier von Waseneck, a family of administrators and castle guards mentioned from 1295 to 1363. Their role tied the site to the local nobility and to the Dukes of Teck, who had built the castle around 1220.

The site lies about 1,250 metres west of Altoberndorf, a district of Oberndorf am Neckar, on a hill rising to 606 metres. The outer moat now serves as a forest road, so the approach follows woodland tracks; wear sturdy footwear for the uneven ground.

Archaeologists uncovered the foundation walls in the 1970s and rebuilt sections of the tower to reveal its original structure. This work allows visitors today to understand how the fortress actually looked.
