Mission Hill Triangle


The Mission Hill Triangle area was originally part of the town of Roxbury, which occupied a prime location as the last town on the mainland before crossing the neck to Boston on the Shawmut Peninsula.  As the advent of turnpike routes, omnibus service, and rail lines improved access from Roxbury to Boston, construction of residential structures to accommodate the area’s growing middle-class population also increased.  Roxbury was annexed to Boston in 1868, leading to further expansion of urban transit systems and additional residential development.

The development of Mission Hill Triangle began in 1872.  The area was subdivided into 190 house lots ranging in size from approximately 1330 to 3000 square feet which were soon developed, primarily with single-family, two-story brick rowhouses, some with brownstone, sandstone, or marble facing.  These rowhouses are typically set back from the sidewalk, allowing for small, landscaped front yards.

Huntington Avenue was cut through the area in 1882, spurring the construction of three-story, multi-family residences at the ends of Worthington and Wigglesworth Streets, and of four-story single family houses on Huntington Avenue.  In 1884 and 1912, Mission Hill Triangle also saw the construction of a four-story hotel and apartment buildings.

The area is remarkably well preserved; nearly all of the structures built after 1872 are still extant.  These houses are visually similar, with most featuring a flat entry bay next to a projecting semi-hexagonal bay, and a flat or mansard roof.  Decorative details between groups of rowhouses vary, with elements of the Queen Anne, Romanesque Revival, Georgian Revival, and Second Empire styles all present in the district.

Mission Hill Triangle remains substantially intact, retaining much its original character and intimacy.  The district serves as both an example of a late-19th century rowhouse neighborhood and of the “streetcar suburbs” that sprang up in and around Boston during that time period.


The Mission Hill Triangle Architectural Conservation District was designated in 1985.
