Southborough is a town in Worcester County, Massachusetts, United States.Its population was 9,767 at the 2010 census, in nearly 3,000 households.
Southborough was first settled in 1660 and was officially incorporated in July 1727. Southborough was primarily a farming community until mills began to tap the small rivers that ran through the town. By the end of the 19th century, Southborough was home to the manufacture of plasters, straw bonnets, boots, and shoes, among other things.In 1727, Southborough split off as the "south borough" of Marlborough, much as Westborough split off fromMarlborough 1717, 10-years before.In 1898 the Fayville Dam was constructed to produce several reservoirs to supply a growing Boston with water. As a result, manufacturing vanished, and Southborough did not see substantial growth until the high-tech boom of the 1970s.The Fay, Burnett, and Choate families along with hundreds of others had a major impact on the development of the town as it is known today. Buildings such as St. Mark's Church, St. Mark's School, the Library, and the Community House and the Fay School were all derived from or were direct products of these families.
