The Old North Church, officially known as Christ Church in the City of Boston, is the oldest standing church building in Boston, Massachusetts. Built in 1723, it is famous for its role in the American Revolution, particularly for the signal lanterns displayed in its steeple to alert the colonists of British troop movements. The church features a beautiful Georgian architecture style and can accommodate around 1,000 worshippers. It is a popular historical site, attracting visitors interested in the American Revolution and the story of Paul Revere, who famously rode to warn of the British advance after seeing the lanterns.
