Dayville Historic District

Dayville Historic District is a preserved area in Killingly containing 21 major buildings clustered mainly around Main and Pleasant Streets, dating from between 1840 and 1912. The district covers roughly 15 acres and is bordered by open land, non-historic houses, and a railroad right-of-way.

The district originated in the 1830s when Captain John Day developed water-powered facilities and built a dam and canal system. This infrastructure enabled the settlement of industrial operations that shaped the area over the following decades.

The district displays houses in various 19th century styles, including Greek Revival structures with gable roofs and Italianate buildings with bracketed cornices. These architectural choices reflect the tastes that were common across New England during that era.

The district is best explored on foot to appreciate the details of the buildings and how they are arranged around the two main streets. The open and wooded boundaries of the area provide clear reference points for visitors seeking to understand its limits.

Behind the Dr. Asahel Darling House, three 19th century outbuildings remain intact: two carriage barns and a well house. These rare survivors offer insight into the everyday life of the district's more affluent residents during that period.
