It feels like it should be the most spectacular church on the road to freedom in Boston, although the church is more mini-pocketed than the cathedral, but its historical significance gives it a higher viewing and historical value, the church's white spire can be seen from afar. The famous signal “If you come by land, light a lamp; if you come by sea, light two lamps” is said to be sent from here onwards, and the church is also known for its signal lights, and there is a bust of Washington in the church.
