A walking tour of downtown Marblehead focusing on the mid-1700s, on the eve of Revolution, when the gritty but thriving and prosperous international Atlantic seaport was the sixth most populous metropolis in British North America. The town’s zealous and nearly fully rebel (Patriot) service in the 8-year war, first on land and then at sea, caused an economic crash that preserved much of the 18th c townscape seen today, including about 300 houses from before 1775 and a significant wooden high-style Georgian municipal building constructed 1727-29.
