Located in Watertown, the Mellette House was built in 1885 by Arthur Calvin Mellette. He was the last Governor of Dakota Territory and the first Governor of South Dakota. The Mellette Memorial Association has restored this home to its former beauty. The original furnishings, family portraits and heirlooms given by the Mellette family make this historic spot unique in the Midwest. We are open 1-5 p.m., Tuesday-Sunday, May 1-October 1. Admission is free. Group reservations are requested.
