Offering as it did (and still does) a panoramic view of Boston and its harbor, Prospect Hill was the site of the strongest of American fortifications during the Siege of Boston in 1775-76. The tower commemorates the site of the raising of the first official flag of the United Colonies — the Grand Union Flag — by George Washington on January 1st, 1776 during the rebels’ year-long siege.
