The civil hospital, a building complex consisting of several wings, has been documented since the beginning of the 14th century, the church was added in the 14th and 15th centuries.
The core of the building was built between the 15th and 16th centuries. In 1331 the Martin chapel was added. The building is provided on the north side with a late Gothic pointed arch portal and a two-lane window with fish bubble tracery. The fresco of a female saint can be seen next to the portal.
The choir of the Bürgerspitalskirche has two two-lane tracery windows. In the nave there is a ribbed vault from the second half of the 15th century. The ribbed vault in the choir dates from the 14th century and is closed by a keystone depicting the Lamb of God.
The famous Martin table from 1518 comes from here, after which its unknown master is named and which can be seen on loan at the Landesmuseum Joanneum. The Martin table is one of the most important late Gothic works in Styria. The memorial is now integrated into the school center of the Federal Forestry School in Bruck and is used for school celebrations.
