The Freedom Trail is a highlight reel of Boston’s most influential historical spots. There are 16 sites on the Freedom Trail. This includes museums, public parks, gravesites, statues and even a three masted frigate ship from 1790! All of these locations are connected by a 2.5 mile long trail that winds through the heart of Boston. The trail is marked on sidewalks and city streets with a red line made with brick or paint.
