Southington Public Library, now known as the Southington Historical Center, is a historic building at 239 Main Street in Southington, Connecticut. The building was constructed in 1902 in a Classical Revival style with glazed terra cotta brick and granite and an original capacity for 6,000 books. Local mill owner and dairy farmer, Lucius V. Walkley, donated half the cost of the building when it opened, and Emma Bradley Yeomans Newell, another entrepreneur, left a bequest upon her death in 1917 for an addition to the library, which was constructed in 1930. In 1974 a new library building was constructed further down Main Street, and the Southington Historical Society took over control of the original library building. The building was added to the National Register of Historic Places in 1989.
