Old North Church (officially, Christ Church in the City of Boston), at 193 Salem Street, in the North End of Boston, is the location from which the famous "One if by land, and two if by sea" signal is said to have been sent. This phrase is related to Paul Revere's midnight ride, of April 18, 1775, which preceded the Battles of Lexington and Concord during the American Revolution.
The church is a parish of the Episcopal Diocese of Massachusetts. It is the oldest active church building in Boston and is a National Historic Landmark. Inside the church is a bust of George Washington, which the Marquis de Lafayette reportedly remarked was the best likeness of him he had ever seen.
Old North Church was built in 1723, and was inspired by the works of Christopher Wren, the British architect who was responsible for rebuilding London after the Great Fire.
