Central to Old Lyme's artistic reputation is this grand late-Georgian-style mansion, which served as a boardinghouse for members of the Lyme Art Colony in the first decades of the 20th century. When artists like Willard Metcalf, Clark Voorhees, Childe Hassam, and Henry Ward Ranger flocked to the area to paint its varied landscape, Miss Florence Griswold offered housing as well as artistic encouragement. The house has been restored to its 1910 appearance, when the colony
was in full flower (clues to the house's layout and decor were gleaned from members' paintings). The museum's 10,000-square-foot Krieble Gallery, on the riverfront, hosts changing exhibitions of American art.
