The Mellette House will open in May 2022.

The Mellette House is the beautifully restored 1885 home of South Dakota's first Governor, Arthur Mellette.  It is a truly unique Watertown experience.

Mellette House was built in 1885 by Arthur Calvin Mellette, last governor of the Dakota Territory and First Governor of South Dakota. The Mellette Memorial Association has restored this home to its former beauty. The original furnishings, family portraits and heirlooms, presented by the Mellette family, make this historic spot unique.  Enjoy your visit as you hear stories of the Mellette family and early Watertown.  Step back in time with us.
