Alt Gutrat (Rossstall) Castle

The castle ruin Alt Gutrat, also known as Rossstall, is a historical site in the Austrian province of Salzburg. Situated on a rocky spur.
The construction of Alt Gutrat Castle is presumed to have taken place in the 12th century, built on a rocky spur on the Tuval, later known as Gutratsberg. It is believed to have coexisted for a period with the later-built Gutrat Castle, possibly until the 13th century. Little is known about its exact function or the reasons for its decline.
The castle ruin Alt Gutrat is located in the municipality of Hallein, in the district of Hallein, within the federal state of Salzburg, Austria.
