Built to protect ships from the Dog Bar Reef, the Dog Bar breakwater was built on top of the ledge. The half mile long breakwater is seven and a half feet above mean high water and ten feet wide, constructed of 231,756 tons of Cape Ann granite over a substructure of rubble. Built by the Army Corps of Engineers between 1894 and 1905 at a cost of only $300,000.00, I wonder what it would cost to build a granite breakwater such as Gloucester’s in today’s economy?
