The visitor center offers guidance to those visiting the city as well as a variety of Sioux Falls souvenirs.

The mill opened in late 1881, consisting of a seven-story main structure built of Sioux quartzite quarried on site.

However, the mill closed by 1883, a victim of inadequate water power and a short supply of wheat.

Oral history has suggested the building was constructed in the late 1800s as a part of a dairy/creamery operation, though there are no historical records to substantiate this.

The barn is now home to the Stockyards Ag Experience, a museum and learning center that connects visitors to agriculture.
