Preservation Planner Lynn Smiledge discusses the history of Paul Revere and the Old North Church. The enduring fame of the Old North began on the evening of April 18, 1775, when the church sexton, Robert Newman, climbed the steeple and held high two lanterns as a signal from Paul Revere that the British were marching to Lexington and Concord by sea and not by land. The Church was built in 1723 and is the oldest standing church in Boston. It is part of the Freedom Trail. www.oldnorth.com
