Stone Wheels

These huge stone wheels (old millstones) can be found all over the grounds at the Tubac Presidio Historic Park, many with varied carved designs. Two wheels would be mounted horizontally on a center post – one was secured and the other could rotate above it – turned by horses or donkeys tethered to a crossbar. The grain was ground between the two wheels.
