Stately 4-bedroom, 3.5-bath 3,869 Sq Ft Colonial, gracefully set on prestigious Prospect Street in the heart of Historic Mystic. Built with the enduring craftsmanship and character of the 1940s, this timeless residence captures the charm and nautical spirit of Mystic's celebrated seaside village lifestyle.

Outdoor spaces evoke the feel of a private coastal retreat, ideal for garden parties, summer entertaining, lawn games, or simply relaxing after a day at the marina. Continued: Attached two-car garage with an additional storage bay provides ample space for kayaks, paddleboards, bicycles, and boating gear. A delightful studio over the garage offers flexible space for guests, artist studio, office, or fitness room, complete with seasonal vistas of the Mystic River. Rarely does an opportunity arise to own such a special home on one of Mystic's oldest, most distinguished, and highly sought-after streets. A true Mystic treasure.
