Granaries are storehouses for threshed wheat, corn, or other crops. A modern version of a granary may be a grain silo. Granaries are often positioned above the ground to protect their contents from rodents and floods. Granaries can be found in castles, towns, and on farms. They may be near windmills or watermills. The food they store for both people and animals can be critical during times of siege or famine. They are home to rats, giant rats, and people that don’t mind living with rats.
