This marble-fronted, beaux arts-style building replicates a state building in Havana, Cuba. It opened here in 1915 as a federal post office, and boasts a central, three-bay, Corinthian-order portico with central pediment set between lower, three-bay, Doric porticoes, all with balustraded parapets and coffered bronze ceilings. This remarkable building pays tribute to the Greek temple.
