Located just off the Rideau Canal side in the heart of Merrickville, the Merrickville Blockhouse is an imposing well-proportioned symmetrical two-storey pyramidal-roofed structure, 4.7 square metres at the base. Constructed for strength with thick masonry walls on the first floor and heavy timbers on the overhanging second floor, the blockhouse retains many defence related elements. The designation is confined to the footprint of the building.
