Il-Fosos
The granaries of Malta, known locally as "Il-Fosos", are networks of subterranean storage chambers historically used to store large quantities of wheat. These structures, primarily located in Valletta, Floriana, Birgu, Senglea, Mdina and Gozo, were crucial in ensuring food security on the Maltese Islands from the medieval period through to the mid-20th century. The Maltese word "Fosos" is plural for "Foss", which in Maltese usually refers to a dry ditch or moat surrounding a fortification, for example, Il-Foss tal-Imdina (the moat surrounding Mdina).
The Maltese granaries resemble the subterranean grain pits of Il Piano delle Fosse del grano (or Piano San Rocco) in Cerignola, Italy.
