Schloss Straßburg, Medieval castle in Straßburg, Austria

Schloss Straßburg is a castle in Austria located at about 754 meters elevation with thick stone walls and towers. The structure displays typical features of Austrian fortified buildings and today contains different exhibition spaces.

Schloss Straßburg was first documented in 1147 as Strazburch, built by Bishop Roman I of Gurk to assert his independence from the Archbishop of Salzburg. It served as the seat of the Bishops of Gurk until 1783, when the residence moved to Schloss Pöckstein. After a damaging earthquake in 1767 and fires in 1858 and 1904, a demolition order was issued in 1954, but restoration began in 1956.

The castle holds a collection of rural objects that show how people in the region lived and worked in earlier times. The displayed furniture, tools, and textiles from different periods give a sense of what mattered to local inhabitants.

The castle stands on a hill above the town of Straßburg, at 754 metres above sea level, so the approach is uphill. It is open to the public, and a restaurant operates inside the building. The courtyard is reached through a Baroque portal of 1685 and the main gate of 1686, built on the site of the Romanesque main gate.

The two Romanesque defensive towers date from the first castle completed under Bishop Roman I (1131–1167), and the old ring wall survives in the outer walls of the west and north wings to a height of about 9 metres. The castle chapel, dedicated to Saint Maurice, was built in the late 12th century.
