Climb 294 stairs to the top of the Bunker Hill Monument to get a bird's eye view of the Boston skyline alongside your history fix. The granite structure, towering more than 200 feet high, is a tribute to one of the first battles of the American Revolution. If you aren't ready for that climb, you can enjoy the green area around the structure and explore the Bunker Hill museum across the street, which is an old branch of the Boston Public Library.
