Boston Common (also known as "The Common") is a central public park in downtown Boston, and the starting point of the Freedom Trail. Dating from 1634, it is the oldest city park in the United States. The Boston Common consists of 50 acres (20 ha). The Common is part of the Emerald Necklace of parks and parkways that extends from The Common to Franklin Park in Roxbury. A visitors' center, with information for all of Boston, is located on the Tremont Street side of the park.
The Freedom Trail is a 2.5-mile-long (4.0 km) path through downtown Boston that passes by 16 locations significant to the history of the United States. Marked largely with brick, it winds from Boston Common to the USS Constitution in Charlestown. Stops along the trail include simple explanatory ground markers, graveyards, notable churches and buildings, and a historic naval frigate.
