The Freedom Road was conceived in 1951 by William Scofield, a prominent Boston journalist, who wanted to make it a way for everyone to travel the city on foot and learn more about the origins of American history. The Freedom Road is paved with a red brick, three kilometers from Boston Park and the Bunker Hill Monument at the end. Along the way, 16 historical sites, including 17th and 18th century premises, churches and American War of Independence sites, are important routes to Boston's historical development, so it is often said that the road to freedom is the best starting point for understanding Boston. It takes about half a day to walk along the route with red marks on the ground, and the historical relics along the way seem to lead you to witness the hardships of people's freedom in that era.
