Originally known as "Upper Gilmanton", Belmont was chartered in 1727 as a parish of Gilmanton. With water power from the Tioga River, it developed as a mill town. Built in 1833, the Gilmanton Village Manufacturing Co. made cotton and woolen textiles. Over the years it would change owners, names and products. In 1921, it was the Belmont Hosiery Co., a maker of silk, lisle and woolen stockings. It went out of business in 1955, and the renovated mill building is now a community center.
