It was named in honor of Colonel William Prescott, who commanded the American forces at the Battle of Bunker Hill.  It was unincorporated on April 28, 1938, as part of the creation of the Quabbin Reservoir.  It was the least populous of the four unincorporated towns, with barely 300 residents by 1900.  Upon dissolution, portions of the town were annexed to the adjacent towns of New Salem and Petersham.  The majority of the former town (the New Salem portion) is still above water, and is known as the Prescott Peninsula.

The Bartow County Courthouse, built in 1902, is an historic redbrick Classical Revival style county courthouse located on Courthouse Square in Cartersville, Bartow County, Georgia, United States.  Designed by the Louisville, Kentucky architectural firm of Kenneth McDonald & Co. together with self-taught Georgia architect J. W. Golucke (James Wingfield Golucke), who is said to have designed 27 courthouses in Georgia and four in Alabama, it is Bartow County's third courthouse and the second one built in Cartersville.  The first courthouse built in Cassville, while the county was known as "Cass County", was burned by General Sherman's troops in 1864.  In 1867 the county seat was moved to Cartersville and the second courthouse was built in 1873.  It proved to be unsatisfactory because court proceedings had to be halted while trains passed by on the nearby railroad.  In 1992 a courthouse annex known as the "Frank Moore Administration and Judicial Center" was completed.  While the 1902 building is still used for some court purposes, most of the proceedings are held in the 1992 building.
