Two fascinating galleries are housed in this 1814 stone mill building downstream from the Hagley Museum. The Somerville Manning Gallery is devoted to 20th- and 21st-century art, including the works of the Wyeth family and other artists trained in the Brandywine School tradition. The André Harvey Studio on the second floor displays Harvey's realistic bronze sculptures of people and animals, as well as sculptural gold jewelry. There's a U.S. Post Office on-site, too.
