Located 30 miles west of Sioux Falls, Porter Sculpture Park was established in 2000. It is an outdoor sculpture park that is visited by tourists from all over the world. There are more than 50 sculptures illustrating the artist’s unique view. The largest sculpture â€“ a bull’s head â€“ is 60 feet tall and weighs 25 tons. It can be seen from Interstate 90. The artist is working on another piece that is even larger. The park is open daily, 7 a.m.-8 p.m., Memorial Day (late May) through September 15.
