An hórreo is a typical granary from the northwest of the Iberian Peninsula, built in wood or stone, raised from the ground by pillars ending in flat staddle stones to prevent access by rodents. Ventilation is allowed by the slits in its walls.

A granary is a storehouse or room in a barn for threshed grain or animal feed. Ancient or primitive granaries are most often made of pottery. Granaries are often built above the ground to keep the stored food away from mice and other animals and from floods.
