Old North Church, Boston, Massachusetts
Old North Church is the oldest church building in Boston, built in 1723, and is still an ongoing Episcopal congregation. Important in American history for its association with Paul Revere's ride as it was from its steeple that the two lanterns signaled the British coming by sea. "One if by land and two if by sea" was the the signal and Paul Revere rode off to warn Samuel Adams and John Hancock and the Minute Men at Lexington. An act that ignited an open conflict with the mother country and flamed into the Revolutionary War.
