Stonington, CTInc. 1649
Stonington is a shoreline town in the southeastern corner of Connecticut, with the historic Stonington Borough — a compact peninsula village of sea captains' homes and narrow streets — as its most distinctive feature. Mystic, the famous seaport village with the Mystic Seaport Museum and Mystic Aquarium, straddles the Stonington-Groton border. The town also includes the more suburban neighborhoods of Pawcatuck near the Rhode Island border.
For property professionals, Stonington is a varied market where the historic Borough commands premium waterfront values, the Mystic area brings tourism-related commercial property, and the Pawcatuck section offers more affordable residential. The Long Island Sound coastline creates flood and storm exposure along the shore.
