America’s first historic walking tour, the Freedom Trail is a path that includes 16 of Boston’s most important Revolutionary War sites. Marked by a line of red paint, the 2.5-mile (4 km) trail starts at the Boston Common, the oldest park in the United States. The tour leads visitors past the Old State House, the site of the Boston Massacre, where British troops fired into a crowd of protesting citizens. It passes by Paul Revere’s House and the Old North Church where two lanterns were hung in the steeple to warn that the British would approach by sea. The end of the path connects with the Harborwalk, leading visitors to the USS Constitution.
