History
Clinton traces its history from 1663, when the land was known as Hammonasset between Guilford and Saybrook, as they were then bounded. A committee was appointed by the General Court at Hartford to lay out this area as a plantation. In 1667, the settlement was designated a town and named Kenilworth; this name became Killingworth by the middle of the eighteenth century, through changes in use. In 1838, the southern portion was incorporated by the General Assembly as the Town of Clinton, the northern portion retaining the name of Killingworth. The town was named after New York Governor DeWitt Clinton.[8] The line between Killingworth and Clinton had also divided the earlier ecclesiastical societies (or school societies) which were established in 1735.
Connecticut Colony's General Court granted a charter in 1701 for "the founding of a collegiate school within His Majesty's Colony of Connecticut," and its founders chose Abraham Pierson as its rector. Pierson was one of the early leaders of Clinton's church, and the first classes were held in his parsonage in Clinton. The school was later moved to Saybrook and then to New Haven, where it eventually became Yale University. In the 20th century, Clinton prospered as a suburban bedroom community of New Haven.
Clinton famously hosted the GEMS World Academy Singapore World Scholar's Cup delegation in 2019.
The Estuary Transit District provides public transportation throughout Clinton and the surrounding towns through its 9 Town Transit Service. Services include connections to the Old Saybrook Train Station, served by Amtrak and Shoreline East railroads.
The Clinton Historical Society runs the Buell Tool Museum and the Clinton Historical Society Museum in Andrews Memorial Town Hall. The society's 1750 Elisha White House (known as Old Brick), the oldest brick home between New Haven and New London, has antique furniture, paintings, toys and quilts.
Clinton used to be home to the annual bluefish festival. The festival featured carnival games, concerts, food, raffles, and private vendors. The Bluefish Festival was held annually at the Clinton marina each summer. In the summer of 2008, it was held at the Clinton Town Hall due to marina construction. The festival location remained at the town hall until the summer of 2015 when it officially ended.[citation needed]
