Asa Gillett House

The Asa Gillett House is a historic house at 202 South Main Street in West Hartford, Connecticut. It is a two-and-a-half story wood frame structure, five bays wide, with a large central chimney. The main entrance, centered on the front facade, is flanked by sidelight windows and pilasters, and topped by an entablature. The house was built around 1760 by Asa Gillett, the grandson of Joseph Gillett, one of West Hartford's early proprietors. It is one of the town's remaining 18th-century homes.

In 1850, the roof was raised on the back of the house, making more rooms upstairs. An addition was also constructed on the back of the house. In 1954, it was referred to as the Tilltson House, possibly after a former owner.

In September 1978, West Hartford citizens William and Carole Carlson purchased the house and owned it for decades.

In 1985, when Connecticut's 350th anniversary took place, the oldest house in each of Connecticut's 169 towns was awarded a plaque, including the Asa Gillett home. The house was listed on the National Register of Historic Places on September 10, 1986.
