Burg Hohenbregenz, Medieval castle ruins on Gebhardsberg mountain, Bregenz, Austria.

Burg Hohenbregenz is the ruin of a high-medieval hill castle on the 598 m Gebhardsberg southeast of Bregenz. Of the medieval structure only the ring wall of the upper castle and parts of the Palas remain; inside that former Palas a pilgrimage church to St Gebhard was built in 1723.

Burg Hohenbregenz was built in the last quarter of the 11th century, before 1097, by the Counts of Bregenz and is first documented in 1209. In 1451 the upper part and in 1523 the lower part passed to the Habsburgs, who made it the seat of Austrian bailiffs. In the early 17th century it was rebuilt as a fortress; in 1647 Swedish troops took it without a fight and blew it up with five mines.

The St. Gebhard pilgrimage church, built in 1723 within the former palace walls, shapes the character of this hilltop. Visitors today encounter a site where religious devotion and medieval ruins coexist.

The site is accessible on foot and offers good views across the surrounding area from its elevated position. Visitors should dress appropriately for weather conditions, as the altitude can affect temperature and wind exposure.

The castle restaurant opened in 1964, built to designs by Willibald Braun and Franz Menia. During the work a cannon from the Thirty Years' War was found, and a Gothic ceiling from Rankweil was installed in the knights' room. A room named after Empress Maria Theresa, with her portrait, recalls the Habsburg period.
