Statement of Significance (as of designation - November 24, 1968):
Probably the finest surviving example of a typical late 18th century New England town, Litchfield was settled in the 1720s and named for the cathedral city in Staffordshire, England. For much of the 1700s Litchfield was an outpost and trading center for the northwest frontier. The town reflects architectural styles of the late 18th and early 19th centuries, as well as the Colonial Revival.

Completed in 1829, the Litchfield meetinghouse anchors the Litchfield National Historic Landmark District. In 2004, it received a $200,000 Save America's Treasures matching grant to repair structural deterioration in the roof trusses, beams, and ties and damage to the interior plaster. This grant will support roof reinforcement and plaster restoration.
