The city of Andover is located in the central part of the state and the southern part of Tolland County. It was settled in the early eighteenth century and in 1848, it was formed from the towns of Hebron and Coventry. The name was transferred from Andover, Hampshire, England. In 1926, investors conceived the idea of building a resort in the swampy area known as Cheney Hollow and formed the Andover Lake Corporation. A dam was built, and in 1927 a lock opened, forming Andover Lake. By the 1940s, several hundred cottages had sprung up around it. Today, Andover remains a small town, rural in nature, centered around the lake.
