Burg Ebertshausen, Archaeological remains near Tegernsee Lake, Germany

Burg Ebertshausen is a medieval castle near Gmund am Tegernsee with visible stone foundations and tower remnants. The site contains the rectangular layout of the main structure along with traces of outer defensive works that once surrounded it.

The site was probably used by Adalbert and Ottokar, founders of Tegernsee Abbey, to secure the monastery's construction; a 33 by 22 metre foundation wall is datable to the 11th century. In 1120 a man named Herbreht acquired the castle, giving it the name Herbrechtshausen, later Ebertshausen. Tegernsee Abbey bought it in 1217 and enfeoffed the Rabenecker family; from 1286 it was held by Wichland of Eurasburg with 52 farms. After two uninhabited centuries, it was razed to the foundations in 1468.

The name Ebertshausen comes from Herbreht, who bought the castle in 1120; it was first recorded as Herbrechtshausen. The site is a Bodendenkmal, a protected archaeological monument, so the 33 by 22 metre wall foundations are visible but not excavated for visitors. The nearby Gut Kaltenbrunn, east of the hill, is thought to occupy the castle's former farm buildings.

Access to the archaeological site is limited since it sits on private property and requires prior arrangements. Visitors interested in exploring the ruins should contact local sources in advance to organize a visit.

The stones from the demolished fortress were scattered throughout the valley and built into local houses and chapels. This recycling of construction materials reveals how medieval communities reused resources from destroyed structures.
