In celebration of the 60th anniversary of the Gateway Arch, Jefferson National Parks Association is proud to announce a public call for entries to a mural design competition. The winning mural will receive $5,000 and be prominently featured in the new Gateway Arch National Park Research Center, located in the historic Old Post Office building in downtown St. Louis. While the Archives Research Room may eventually relocate, the mural will serve as a significant public-facing feature during this phase of the Center's development. Documentation of the mural will be preserved as part of the archival record, ensuring the work remains accessible to future researchers and visitors even after the physical display concludes. The competition runs from June 23 through July 25, 2025. Artists located in the greater St. Louis metropolitan area are invited to submit an original design that interprets the park's rich historical themes, including Thomas Jefferson's vision of the American West and the civil rights history of the Old Courthouse. The winning submission will be announced by August 15. The selected mural must be installed by the artist in the Research Center’s Archives Reading Room by September 15, with an official unveiling during the park’s anniversary celebrations in October.
