South Boston is a densely populated neighborhood of Boston, Massachusetts, located south and east of the Fort Point Channel and abutting Dorchester Bay. One of America's oldest and most historic neighborhoods, South Boston was formerly known as Dorchester Neck, and today is called "Southie" by residents. Long known as a working class Irish-American neighborhood, it is also home to the Boston area's small but vibrant Polish and Lithuanian communities. South Boston contains Dorchester Heights, where George Washington forced British troops to evacuate during the American Revolutionary War. Home to some of the oldest U.S. housing projects, South Boston has more recently seen property values join the highest in the city.
