Vernacular architecture in Soajo and in Lindoso is internationally known, due to the unique characteristics of the granary structures (espigueiros) and the communitarian threshing-floors (eiras). The main function of the granary is to dry agricultural products, especially maize. These granaries are located in communitarian spaces, which are exposed to wind in order to facilitate the drying of the maize. Morphologically, the granaries have a rectangular shape and a high standing volume.
