When visiting with Fayetteville locals and University of Arkansas graduates of every generation, mention of the “Old Post Office” or the “OPO” brings forth a multitude of memories relating to the vintage 1911 centerpiece of the Historic Fayetteville Square. Since the last mail was delivered from the building in the 1970s and the site was placed on the national register of historic places, the OPO has been a home to an array of businesses and provided a beautiful backdrop to countless photo ops.
