Friesach’s four-storeyed medieval granary was built in the first quarter of the 14^th century CE.

A two-storeyed arcaded porch (facing the courtyard) was added to the rear part of the building in the 16^th century. The northern and eastern facades of the granary are a part of Friesach’s fortified curtain wall. 

The granary has an enormous storage capacity. Taxes-in-kind (including grain) were collected from the subjects in the region and stored in this huge granary. This system lasted until the end of Salzburg’s rule.
