Lyme is a small, affluent town on the Connecticut River, known for its connection to American Impressionist art — the Lyme Art Colony was based here, and the Florence Griswold Museum preserves that legacy. The town's landscape of marshes, river frontage, and wooded hills has been painted by generations of artists.
For property professionals, Lyme is a high-value, low-density market where the artistic heritage, river setting, and deliberate preservation create a distinctive property environment.
