The first brick granaries were built in the 14th century, constructed as a compact, continuous line of structures. In that time, they served as grain warehouses and defensive buildings; after their reconstruction in the 19th and 20th centuries, several of them were turned into residential buildings. The majority of granaries date from the 16th–18th centuries. From the side of the Vistula River, they are multi-story buildings, supported by tall buttresses, and from the direction of the city (Spichrzowa Street) – mostly two-story buildings. Several of them have facade of common tenement houses. Wood structures and beam ceilings are usually well preserved inside these granaries. One of the titbits is cannonballs built in exterior facades.
In 2017, the granaries were awarded the title of Monument of History.
Currently, some of the granaries are part of the complex of buildings of the Museum of Grudziądz and the Flis Museum of Vistula Trade.
