Thomaston Town Hall is located at 158 Main Street, Thomaston, CT 06787; phone: 860-283-4141.
Once part of the Town of Plymouth and known as Plymouth Hollow, Thomaston was incorporated in 1875, making it one of the youngest municipalities in Connecticut.
Eli Terry opened a clock factory here in 1810 and in 1814 introduced a clock known as the "patented wood shelf clock," which were produced by the hundreds of thousands. In 1812 Seth Thomas, formerly associated with Terry, set up a factory whose clocks enjoyed a worldwide market. The village where the factory was located began to be known as Thomas Town. A grand view of the village and surrounding countryside is found on Latin Hill about 3 miles west of the village.
