The University of Arkansas Campus Historic District is a historic district that was listed on the National Register of Historic Places on September 23, 2009. The district covers the historic core of the University of Arkansas campus, including 25 buildings.The district was added to the National Register of Historic Places (NRHP) on September 23, 2009 and the listing was announced as the featured listing in the National Park Service's weekly list of October 2, 2009. The Inn at Carnall Hall is a member of Historic Hotels of America, the official program of the National Trust for Historic Preservation.The historical core of campus was built in many phases, coincident with when funding was available to build. Beginning with the construction of Old Main in 1879, buildings were built haphazardly around campus. This was changed when the architecture firm Jamieson & Spearl designed the 1925 master plan, which includes many of the Collegiate Gothic style buildings (such as the Agriculture Building). The plan allowed for more structure and a better layout. However, funding ran dry and the master plan came to a halt. Building resumed following many Public Works Administration grants after World War II.
