While in Watertown, the Terry Redlin Art Museum is really good to see and they have recently finished restoring the old opera house downtown. It is called the Goss Opera House. I have not been there yet, but have really wanted to go. The Mellette House is also something I enjoyed while there.
Depending on how far you want to go outside of Watertown (and perhaps how well you like history), the old school for the blind in Gary, SD has also recently been restored. It is called Buffalo Ridge.
