The Museum of Automobiles opened in 1964 for future governor Winthrop Rockefeller to display his personal car collection. Today it boasts antique and rare vehicles, including the only two Arkansas-made Climber cars still in existence. But visitors should not overlook the architecture. To create an open space for display without the need of interior support columns, the Little Rock architecture firm of Ginocchio, Cromwell, Carter, Dees, & Neyland suspended the roof using a tensile cable system hung from four corner columns connected by cast-concrete beams that form a compression ring at the outer perimeter. The result was a dramatically styled modern structure. As an early and important example of tensile-cable construction in Arkansas, the building was listed in the National Register of Historic Places with statewide significance in 2019.
