The Stonington Free Library Association first met in 1887 and, the following year, established a library in Stonington Borough, located initially in a house on the corner of Main and Church Streets. Outgrowing this space, a new library building was constructed in Wadawanuck Park, on land donated for the purpose by the heirs of Samuel Denison. Opened in 1900, the new library was designed by Clinton and Russell of New York. The Stonington Free Library was expanded to the north in 1956 and again in 1990, with the addition of the Wimpfheimer Wing.
