The Freedom Trail is a 2.5 mile red path that leads to 16 historical sites through downtown Boston in Massachusetts. The trail is a collection of historical buildings and events that tell the story of the American Revolution. The trail starts at the Boston Common, which is the oldest public park in the US. The Boston Common served as a cow pasture and a military camp. Today, this area is used for musical performances or you can use it as a picnic area. The trail includes such buildings as the Old State House, which housed the government of colony and state. The Declaration of Independence was read from its balcony. The Paul Revere House is probably the highlight of the trail. The house displays the 17th and 18th century furnishings and artifacts, including silver. Paul Revere had 16 children calling them lambs. He supported his family with his trade in silver. Almost at the end of the trail, there is the USS Constitution, the world’s oldest floating ship that traveled to the edges of the world and participated in the Barbary Wars. Today, the ship is permanently harbored in the Charlestown Navy Yard. However, it visits Boston’s Harbor every 4th of July and for occasional events. The trail ends at the Bunker Hill Monument.
