Bunker Hill is the fortified hill where colonial forces fought the Royal Army in 1775, a symbol of resolve in the Revolution.
Archaeologists guided by a 1775 map have uncovered a defensive trench and artifacts dating to the Battle of Bunker Hill in Boston. Musket balls, gun flints, teacups and other items reveal how the fortifications were built and used, with no human remains found so far. The dig continues through the Fourth of July.
