Jagdhaus Breitenbrunn, Medieval hunting lodge ruins in Breitenbrunn, Germany

Jagdhaus Breitenbrunn is a ruined hunting lodge and former watchtower in the Ore Mountains, standing southwest of the church at the upper end of Breitenbrunn. Its walled rectangular core measures about 13 by 20 metres and rises 1 to 1.5 metres above the water, with a tower ruin of roughly 9 by 9 metres inside and a water-filled moat about 3 metres wide around it.

The site likely began as a watchtower with a moat from the founding period of the Schwarzenberg lordship, which became the starting point for the settlement of Breitenbrunn. The tower was later converted into a hunting lodge, accommodation and storage for hunting equipment, also serving as the forester's residence. It burned down in 1610 and again in 1617, was rebuilt, and after 1700 fell into ruin. In 1891 the local chief forester had the ruin and moat secured.

The site reflects the bond between nobility and hunting pursuits in the Ore Mountains. Visitors can observe how such structures served as gathering places for the region's landowning families.

The ruins sit within a park area on the edge of Breitenbrunn village and function as a starting point for hiking trails through the region. Access is straightforward, and the location offers good opportunities for exploring the surrounding countryside on foot.

During restoration work in 1891, workers uncovered a 17th-century drinking glass among the ruins. This discovery provides clues about the former wealth and daily habits of those who lived there.
