Freedom Trail attraction. One of Boston’s most iconic sights is, ironically, a misnomer: the Bunker Hill Monument actually sits atop Breed’s Hill, where the American Revolution’s Battle of Bunker Hill took place in 1775. The ill-equipped colonists were ultimately defeated in battle, but caused considerable damage to British forces. The towering, 221-foot obelisk is a reminder of these patriots’ bravery. Climb to the top for terrific views (free, but April 1-June 30 must pick up a climbing pass at Bunker Hill Museum). Open daily 9 am-5 pm, last climb at 4:30 pm.
