Welcome to one of the smallest memorials on the Freedom Trail, and one of the most consequential. Look down at the traffic island in front of the Old State House, right beneath its balcony. You will see a ring of stones set into the pavement, with downtown Boston rushing around it. That ring marks the Boston Massacre Site. On the night of March 5, 1770, this spot, then part of King Street, became the scene of a confrontation between British soldiers and a crowd of colonists. Five colonists were killed by gunfire. It is easy to walk past the marker without noticing it. Once you know the story, though, you will find it hard to look at this intersection the same way again. The area around you is now the Financial District, with commercial buildings, subway station entrances and a constant flow of pedestrians. In the next few minutes we will look at the tensions that led to that night, the people who died, the way the event was turned into a political message, and a courtroom surprise that followed. Take a moment to find the circle of stones, and keep an eye on the traffic while you do.
