Old North Church The Old North Church, built in 1723, was the location where Paul Revere had signal lanterns lit on the night of April 18, 1775, prior to his "midnight ride" that led to the Battles of Lexington and Concord and the start of the revolutionary war. The church, the oldest operating in Boston, has an Episcopalian congregation, which owns and operates the building. Old South Meeting House The Old South Meeting House, built in 1729 was the site of numerous pre-revolutionary meetings, including one, attended by a crowd estimated at more than 5,000, on the evening prior to the Boston Tea Party in December 1773. It served as a church until 1877, when it became a museum operated by a nonprofit organization dedicated to its preservation. Old State House The Old State House is the oldest municipal building in Boston. Built in 1713, it was the seat of the Colonial government, and afterward the State government, until 1798. The Boston Massacre took place in front of the building in 1770. In 1881 it was saved from destruction by the Bostonian Society, which was formed specifically to preserve it. The society still operates the City owned building as a museum. The Boston Massacre is reenacted regularly under the society's auspices.
