Feistritz Castle, Medieval castle in Feistritz am Wechsel, Austria.

Feistritz Castle is a narrow, north-south oriented complex enclosed by a ring wall, with a Romanesque palas on the north side and a bergfried projecting outside to the northeast. Three round corner towers survive from a late Gothic rebuild around 1500, and a west gate tower with drawbridge dates from after 1685.

Built probably in the second quarter of the 12th century by ministeriales, the castle passed from the Pottendorfers (to 1488) to the Zinzendorfers (to 1537), then to the Rottal family in 1547 and the Pergens in 1681. Sieges in 1485, 1529 and 1683 failed. Maximilian Mautner bought it in 1922 and restored it with architect Marischka until 1924; after 1960 it became a conference centre.

The castle has belonged to the Reichhold family since 1965 and is open to the public for conferences and seminars. After 1960 the complex was adapted into a conference centre, so the rooms now host meetings rather than concerts. The name Feistritz comes from the village of Feistritz am Wechsel, which the castle overlooks from the southeast.

The location is accessible and offers accommodation along with spaces for various events, with architecture to explore across multiple levels and different entrances. Visitors should expect uneven floors and steep stairs typical of an older medieval structure.

The castle was besieged in 1485, 1529 and 1683 and never taken. After World War II the Red Army occupied it and used it as a mess hall for Russian officers; it was returned to its Austrian owners only in 1955, and since 1965 it has belonged to the Reichhold family.
