Old North Church is the popular name for Christ Church, the oldest public building in Boston. The red-brick structure has a slender white steeple in the Christopher Wren style. Church sexton (caretaker) Robert Newman hung two lanterns there as a signal from Paul Revere that the British were coming to seize arms and gunpowder at Concord, Massachusetts, at the start of the American Revolution (1775-1783). The tower contains the first set of church bells in the American Colonies, cast in 1744. Storms in 1804 and 1954 toppled the spire. In 1955, it was rebuilt to its original height of 190 feet (58 meters).
