Minot’s Ledge Lighthouse

Minot's Ledge Lighthouse is located off Cohasset, Massachusetts, in the United States. The original lighthouse was constructed in 1850 but was destroyed by a severe gale in April 1851, just a year later. The current Minot's Ledge Lighthouse has been maintained since 1860. This granite tower stands 89 feet tall on a reef that is only exposed at low water. Its construction took five years and cost £62,500, with stones dovetailed vertically to form a conical frustum shape. The construction of lighthouses on open-sea sites, like Minot's Ledge, became more common around 1700 as structural and lighting improvements advanced.12
