Boston - Siege of Boston Fortifications

This tour follows the points on the National Park Service website (link below)

During the Siege, many of those loyal to the British government remained confined inside Boston. This included the artist Henry Pelham. With a pass from British authorities, Pelham surveyed and observed the defensive lines inside Boston and throughout Boston Harbor. When mapping the areas outside of British control, Pelham relied on careful observations and personal memory to map the roads, houses, and terrain of the communities of Roxbury, Dorchester, Brookline, Cambridge, and Medford. In the end he created a map that depicted, with great detail, what the siege lines looked like surrounding Boston.

Like many loyalists, Pelham evacuated Boston after the siege. He ultimately settled in London and published his map "A Plan of Boston in New England with its Environs..." in 1777. Using other primary sources, secondary accounts, as well as the surviving terrain and landmarks in the area, we used Photoshop and GIS resources to manipulate and correct Henry Pelhams’ work so that it fit accurately on a modern digital map.
