Freetown, Wales and then Monmouth
Families from Brunswick settled here as Freetown in 1776 and 1777, on land of the Plymouth Patent. The place was also called Bloomingborough and Wales before the Massachusetts General Court incorporated it as Monmouth on January 20, 1792. The name came from landowner General Henry Dearborn, who had fought in the Battle of Monmouth in New Jersey on June 28, 1778.
Monmouth was considered one of the best agricultural towns in the state, raising hay, apples and potatoes along with beef cattle and dairy products, and it had good sites for watermills. The Androscoggin & Kennebec Railroad, later part of the Maine Central, opened to the town in 1849. By 1859 Monmouth had two factories making boot-webbing and binding, a shovel and hoe factory, a tannery, a carpet factory and a sleigh and carriage factory, among other shops.
Cumston Hall and the Academy
Cumston Hall, at 796 Main Street, was finished in 1900 as a gift to the town from Dr. Charles M. Cumston, a former headmaster at the English High School in Boston. He chose Harry Hayman Cochrane, a muralist who had gone to school in Monmouth, to design and decorate it, and Cochrane’s work is most noted in the cherubs on the ceiling and the molded plaster around the stage. A square tower about 70 feet tall rises from one corner. The hall is home to the Cumston Public Library and the Theater at Monmouth, and it’s on the National Register of Historic Places.
Monmouth Academy was founded as a private school in 1803, and its brick building with a belfry went up in 1855. In 1976 the academy became the town’s public high school.
