Most people think you have to travel to Europe to see the ruins of stone castles, but there is one right here in Missouri! The park that protects the ruins is also a geologic wonderland featuring sinkholes, caves, a huge natural bridge, sheer bluffs and Missouri’s 12th-largest spring. The park is also near Lake of the Ozarks and Ha Ha Tonka Spring. One of the most accessible outdoor parks in Missouri, a series of boardwalks and trails make it easy to explore the park's many points of interest. To celebrate this iconic American landmark and its many curious features, the artists of Anderson Design Group have made this classic design and vintage poster harkening back to 20th-century travel art, ready for you to enjoy as a poster, canvas, metal sign, postcard, or note card.
