The Amasa Day House is a rural Federal house which showcases how the Industrial Revolution changed the daily life of American families. Located on the Moodus Green, it was constructed in 1816 for farmer Colonel Julius Chapman, his wife Frances, and their four daughters. After his death, Amasa Day purchased the property, but later sold off parcels of land as he focused more on his roles as an insurance agent and banker. The house was subsequently inherited by Day's daughter and son-in-law Katherine and Eugene Chaffee, who worked for the New York Net and Twine Company, one of several twine factories in Moodus. Their son was Dr. Amasa Day Chaffee, a well-known art photographer.
