Chestnut Hill is a town situated six miles (9.7 km) west of downtown Boston, Massachusetts, United States. Like all Massachusetts towns, Chestnut Hillside is not an incorporated metropolitan entity. It lies partially in Brookline in Norfolk County; partially in the city of Boston in Suffolk Area, as well as partly in the city of Newton in the Middlesex Area. Chestnut Hill Massachusetts‘ borders are specified by the 02467 ZIP Code. The name describes several small hills that neglect the 135-acre (546,000 m2) Chestnut Hillside Storage tank instead of one certain hill. Chestnut Hillside is best known as the home of Boston College, part of the Boston Marathon route, in addition to the Collegiate Gothic canvas of landscape designer Frederick Legislation Olmsted.

While most of Chestnut Hillside continued to be farmland well into the very early 20th century, the area around the reservoir was developed, in 1870, by landscape engineer Frederick Regulation Olmsted, developer of Central Park in New York City and of the Emerald Green Necklace in Boston and also Brookline.

Due to the relevance of its landscape and also design, the National Register of Historic Places, in 1986, assigned parts of Chestnut Hillside as historical areas. Examples of Colonial, Italianate, Tile, Tudor Rebirth, and Victorian architectural designs are evident in the town’s country estates as well as estates. The Boston College campus is itself a very early instance of Collegiate Gothic design.
