Charlestown is a neighborhood of Boston, Massachusetts, United States.It is located on a peninsula to the north of the Charles River, across from downtown Boston. Charlestown was originally a separate town and the first capital of the Massachusetts Bay Colony; it became a city in 1848 and was annexed by Boston on January 5, 1874.
While it has had a substantial Irish American population since the migration of Irish people during the Great Irish Famine of the 1840s, since the late 1980s the neighborhood has changed dramatically because of its proximity to downtown and its colonial architecture. However, it still maintains a strong Irish American population and identity.
Charlestown contains several places of historical interest, many of which are marked by the northern end of Boston's Freedom Trail. The Freedom Trail ends at the Bunker Hill Monument commemorating the famous Battle of Bunker Hill. The USS Constitution, the oldest commissioned vessel in the US Navy, is docked in the Charlestown Navy Yard.
Charlestown was also the location from which Paul Revere began his famous "midnight ride" before the Battles of Lexington and Concord. A restaurant opened in 1780 and still in operation, Warren Tavern, claims to have been one of Revere's favorite taverns. Of Charlestown's churches, St. Mary's (1887–1893) is considered one of the masterpieces of Patrick Keely.
