Officially named Christ Church, Old North Church is the oldest church building in Boston, Massachusetts. The design is in the style of Sir Christopher Wren. The steeple fell in hurricanes in 1804 and 1954. The current version is an exact copy of the original. The 190-foot spire, long a reference point for sailors, appears on navigational charts to this day. The famous "One if by land, and two if by sea" signal is said to have been sent from this church.
