Burgruine Bachsfall, Medieval castle ruins in Bischofshofen, Austria

Burgruine Bachsfall is a castle ruin on the orographically right bank of the Gainfeldbach in Bischofshofen, named after the nearby Gainbach waterfall. What remains is a stretch of castle wall on a plateau of roughly 30 by 30 metres, excavated, uncovered and secured between 1983 and 1985. An idealized depiction of the former castle is painted on the house at the waterfall.

The castle was founded by the Lords of Pongau in the 12th century. When the ministerial family of Burg Gutrat received the Landrichteramt (judicial office) in Pongau in 1230, they appear to have been seated at the tower on the Gainbachfeld. Later records are lacking. The stones of the residence are said to have been used to build the Bischofshofen cemetery chapel in 1522.

The ruin takes its name from the Gainbach waterfall beside it, on the orographically right bank of the Gainfeldbach. The site is a protected monument (Denkmalgeschütztes Objekt). On the house at the waterfall, an idealized painting shows what the castle once looked like.

From Bischofshofen, drive to the ski jump on Gaisberggasse and park there. A signposted trail leads to the ruin in about 30 minutes, either via the steps at the Gainbach waterfall or along a gentler descent.

The house by the Gainbach waterfall bears an idealized painting of the castle as it once stood, giving visitors a picture of the lost structure. The ruin itself is a protected monument in the state of Salzburg.
