Mattapan in Boston
Mattapan is in Boston. Historically a section of neighboring Dorchester, Mattapan became a part of Boston when Dorchester was annexed in 1870. Predominantly residential, Mattapan is a mix of public housing, small apartment buildings, single-family houses, and two- and three-family houses (known locally as "Three-Deckers" or "Triple-Deckers"). Blue Hill Avenue and Mattapan Square, where Blue Hill Avenue, River Street, and Cummins Highway meet, are the commercial heart of the neighborhood, home to banks, law offices, restaurants, and retail shops. Mattapan now has the largest Haitian community in Massachusetts, and is also largely made up of African Americans and immigrants from other Caribbean countries.
The Mattapan-Ashmont trolley line (a branch off the Red Line) of the MBTA serves Mattapan as well as several bus routes. The Fairmount Line of the MBTA Commuter Rail also serves Mattapan at Morton Street, providing service to downtown Boston and the suburbs.
