The granary was built in the first quarter of the 14^th century CE. It was used to store the grain delivered by Carinthian subjects until the end of Salzburg’s rule. In 1582, the building was partially destroyed by fire. 

The granary is a four-storeyed building built in the northeast corner of the town wall between two older defensive towers from the 13^th century. The outer facade is formed by the town wall.

A two-storeyed pillar arcade porch with a pent roof (lean-to roof) was added to the west side in the second half of the 16^th century. The former stables were on the ground floor.
