The building, made of local tuff stone, is spread over two levels: the upper floor, with tall lowered-arch windows, was used for drying grains, while the ground floor stored provisions for the population and animals during times of scarcity. The thick walls, nearly one meter wide, ensured a stable microclimate, preventing thermal fluctuations that could compromise the quality of the wheat.
Inside, a barrel vault in exposed brick showed traces of lime and cocciopesto plaster, while the terracotta floor with drainage channels for moisture is still visible in some sections. A system of pulleys and rail-mounted wheelbarrows, integrated into the loading bays, facilitated the handling of grain sacks.
In the 19th century, with the abolition of feudal rights, the granary became a municipal warehouse and later a storage space for farming tools: to this phase date the popular graffiti etched into the walls, with names and dates recording the memory of those who passed through. Recently, thanks to a valorization project financed by the European Regional Development Fund, the granary has been restored, recovering the plasterwork and consolidating the vaults, and transformed into an exhibition space dedicated to the themes of historical nutrition and food security.
