America's oldest public park, Boston Common has a long and storied history, serving as a campground for British troops during the Revolutionary War and as green grass for cattle grazing until the 1830s. Nowadays, the Common is a place for picnicking and people-watching. In winter, the Frog Pond attracts ice-skaters, while summer draws theater lovers for Shakespeare on the Common. This is also the starting point for the Freedom Trail.
The on-site information kiosk is a great source of information, maps and tour guides. Otherwise, wander freely about this 50-acre green, crisscrossed with walking paths and dotted with monuments. Bostonians hustle to and from the nearby T (subway) stations; others stroll leisurely, enjoying the fresh air or engaging in any number of Common activities, from free concerts to playground shenanigans to seasonal festivities.
