Located at the historic Moore-Dalton House, the Margaret Harwell Art Museum collects contemporary art by Missouri artists and offers a wide range of programs and exhibits throughout the year. The museum, which opened in 1979, is one of only five art museums in the state. It offers art classes as well in wood carving, pottery, painting, and others. Lectures, concerts, and workshops are offered as well. The house is listed on the National Register of Historic Places.
The house was built in 1883 by Thomas H. Moore as a one-story residence. He added the second floor in 1890. The house underwent further changes, giving it its current Neo-Classical appearance, after James L. Dalton bought it in 1896. Dalton made a living as a businessman, served a term in the state legislature, and invested in manufacturing.
