Watch the opening battle of the American Revolution take place right before your eyes at Minute Man National Historical Park. This hallowed ground is where the war began and where it is relived through reenactments. These demonstrations aren't the only things to do at the park though; explore the visitors center, walk down Battle Road Trail, check out the Hartwell Tavern and The Wayside and other park attractions.
The Riverway is a parkway that connects the Back Bay Fens and Olmsted Park, making it an important piece of the Emerald Necklace park system. Throughout the park, there are several historic bridges and hiking and walking paths, including the Bridle Path that was used by equestrians to cross the river. The Riverway offers a nice outdoor escape from the hustle and bustle of Brookline Avenue.
