Blue Anchor Tavern

Cambridge, MA

Built in 1763 by the Province of Massachusetts Bay, Hollis Hall has sheltered Harvard students for more than two centuries and honors the Hollis family of London, whose generosity sustained the college for generations. In 1775-76 the building traded scholars for soldiers, serving as barracks for colonial troops during the siege of Boston.

Cambridge, MA

In the opening year of the War for Independence, the town of Cambridge sat at the heart of the Siege of Boston, its colleges, homes, and commons pressed into service as barracks, hospitals, and command posts for the newly gathered American army. Elegant houses whose owners had fled were commandeered as officers' quarters and headquarters, making quiet residential streets the nerve centers of a revolution. A marker like this one fixes the spot where such a headquarters once stood, connecting an ordinary Cambridge address to the improvised military capital of 1775–76.

On April 19, 1775, the war for American independence began at dawn on Lexington Green and spread down the road through Concord. The bloodiest hours came not in the morning volleys but during the British column's long, harried retreat toward Boston, when militia and townsmen fired from behind walls and houses along the route. Cambridge lay squarely on that path, and here four of its citizens fell to the retreating regulars. The city raised this monument in 1880 to mark the ground and keep their names — Isaac Gardiner, William Marcy, John Hicks, and Moses Richardson — from fading.

Somerville, MA

In 1775 and 1776 the hills around Charlestown and Boston bristled with earthworks as the Siege of Boston opened the Revolutionary War. This map recalls the fortifications thrown up across the landscape—including the heights where the Battle of Bunker Hill was fought—while colonial forces hemmed in the British-held town. The ground it depicts is now Somerville and its neighbors, though the ridgelines that shaped the siege remain.
