The Square Heritage Conservation District is a key area within the larger footprint of the historically significant Goderich downtown core. It is located on the eastern shore of Lake Huron on a bluff that overlooks the Maitland River to the north and east. The harbour and beach areas are to the west. The design and development of the downtown area took place between 1840 and the mid-1890's on the bluffs above the original 1827 port settlement. The Square's unique radial composition and ordered symmetry is centred on an octagonal shaped park where the 1950s Art Deco courthouse stands. The historic architecture is illustrated by Georgian, Italianate and Second Empire styles and detailing.
