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 the oldest neighborhoods in the United States, South Boston is most popularly known as Southie. Although still popularly known as a working class Irish American neighborhood, it is also home to the Boston area's small but vibrant Polish and Lithuanian communities, and its demographics are rapidly changing. South Boston contains Dorchester Heights, where George Washington forced British troops to evacuate during the American Revolutionary War. South Boston has undergone gentrification, and consequently, its real estate market has seen property values join the highest in the city.
