Colonel Julius Chapman created a symbol of rural gentility by building this Federal-style house in 1816 on the Moodus Green. It was subsequently purchased by Amasa Day, a local banker, in whose family the house remained until 1967. The house is furnished largely with objects owned by members of the Day family, including toys and locally produced ceramics and silver, and still features the original floor and stair stenciling applied to mimic carpeting. Also on display are a selection of photographs from among the thousands taken by pioneering American Pictorialist art photographer Dr. Amasa Day Chaffee between 1890 and 1925.

The house offers exhibits and tours.

With its diamond-paned casement windows, clapboards weathered nearly black, and hewn overhangs, the Buttolph-Williams House harks back to the Puritan pioneering of New England during the 1600s. Although actually built around 1711, the house reflects the continuing popularity of traditional architecture. As a result it is considered the most faithful restoration of a 17th-century-style Connecticut Valley house. An array of colonial-era furnishings is on display. Highlights include a room designed and decorated by Katherine Prentiss Murphy, one of the 20th century's most renowned antiques collectors, and a kitchen with an enormous open hearth and an assortment of Colonial-era cooking implements.

In 1639, a group of Puritans led by their minister, Reverend Henry Whitfield, built the stone house in which this museum is housed. As well as serving as a home for the Whifield's, it was also a fort for the community. Its massive stone walls and chimneys, steeply-pitched roof, and casement windows reflect the style of post-medieval domestic architecture found in England—rare in 17th-century America and unique today. It is Connecticut's oldest house and New England's oldest stone house.
