The town of Suffield is in the center of Connecticut's border with Massachusetts. It is in fact bordered on two sides by Massachusetts, owing the trant of land lying between Suffield and Granby never annexed from Massachusetts. Along with four other towns in Northern Connecticut, Suffield was incorporated as a town by Massachusetts in 1674, but boundary disputes persisted until 1803. Suffield covers 43.1 sq. miles and is home to 11,320 residents.
