The granary is a landmark building located adjacent to Wyspa Biskupia. It was built at the turn of the 19th-20th century in neo-Gothic style. It is one of the town’s most interesting landmarks, as evidenced by the numerous engravings, paintings and postcards illustrating it. It has four storeys and impressive dimensions of 47.5m by 13m. The building is unplastered and the high gabled roof is tiled.
The granary was built as a beam structure with a brick infill. The ground floor of the building was made of clay brick and set on a stone plinth. The timber elements were joined with straight or diagonal mortises and interlocks. There are braces at the corners and in the middle of the walls and carpentry marks are visible on the structure. Inside, the granary has preserved beamed ceilings and two rows of columns with joists.
After the war, the building was used by the State Agricultural Farm (PGR) as a grain warehouse until 1989. Today, the granary is in private hands and its owner is planning to carry out a general renovation and adapt it for hotel purposes. The building will be part of a larger complex comprising developments around Wyspa Biskupia. The structure can currently only be viewed from the outside as entry is prohibited.
