The first settlers of Washington City built granaries to store dry grains, tools, wine and other items. The sandstone and black lava rock in the building now known as the Granary came from the Morgan Adam Granary, which was originally located at 60 South 100 West in Washington. The original granary was slightly smaller than this building and had air holes instead of windows. Some of the Granaries used in Washington were used not only for food storage but for family living space and, on one occasion, a school.
George Crawford built the granary for Andrew Sproul.
