Belmont was established on March 10, 1849, by former citizens of, and land from the bordering towns of Watertown, to the south; Waltham, to the west; and Arlington, then known as West Cambridge, to the north. They also wanted a town where no one could buy or sell alcohol (today, a person can buy alcohol in this town). The town was named after "Bellmont", the 200 acre (0.8 km2) estate of the largest donor to its creation, John Perkins Cushing. Cushing Square is named after him and what was left of his estate after it nearly burned to the ground became a Belmont Public Library branch. The easternmost section of the town, including the western portion of Fresh Pond, was annexed by Cambridge in 1880 in a dispute over a slaughterhouse licensed in 1878 on Fresh Pond, so that Cambridge could protect Fresh Pond, a part of its municipal water system.
