About Killingworth

Killingworth, in Middlesex County, is located in south-central Connecticut and includes Chatfield-Hollow State Park. Europeans established a plantation here in 1663, naming it Homonoskit after the Hammonasset people who inhabited the area. In 1703, the state General Assembly authorized the establishment of the town of Kenilworth, which eventually became known as Killingworth. Its original lands extended to the coast and included present-day Clinton until 1838. Historically, Killingworth was an agricultural community, but it is a rural residential area today. Among its famous residents is the infamous Abel Buell. This eighteenth-century forger and inventor engraved one of America's first maps and invented the first lapidary or gem-cutting machine.
