Kingston Mills Block House

In 1832 the construction of a blockhouse was started, one of only four built along the Rideau. It was completed in about 1834. It was built to the same dimensions as those at Narrows and Newboro, 24 feet (7.3 m) on a side, designed to accommodate 20 men. It was built with a masonry base, about 3 feet (0.9 m) in thickness, with an upper storey, 28 feet (8.5 m) on a side, built of large squared timbers. Access was by a stairway to the second floor.

This is where they garrisoned about 20 troops to guard the Kingston Mills. Just down the hill is a waterfall near a power house.
