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,[citation needed] South Boston is most popularly known as Southie. Southie is full of rich history and culture. Once a predominantly working class Irish Catholic community, in recent years South Boston has become increasingly desirable among young professionals and families who are attracted to the neighborhood's strong sense of community and quick access to downtown and public transportation.
