The Bunker Hill Monument is not on Bunker Hill but instead on Breed's Hill, where most of the fighting in the misnamed Battle of Bunker Hill actually took place. The Monument Association, which had purchased the battlefield site, was forced to sell off all but the hill's summit in order to complete the monument. An exhibit lodge built adjacent to the monument in the late 19th century houses a statue of Warren and a diorama of the battle. Bunker Hill is one of the sites along the Freedom Trail and is part of Boston National Historical Park.
