On the grounds of Haan Museum is a sculpture garden. It includes over twenty sculptures from notable Indiana artists. The sculptures range in form and media, including: bronze, stone, clay, and steel. Most pieces are under 8 feet tall to provide guests with a more intimate experience. It is free and open to the public every day, complementing the nature trail that is on the Museum grounds. The nature trail is home to 30 species of native Indiana trees, identified and labeled. Visitors can learn more about the art in the Garden, but also enjoy some of Indiana's natural beauty, as well.
