Federal Hall was the first capitol building of the United States of America. It is located at 26 Wall Street in New York City and, having been replaced in the 19th Century,served as the first United States Customs House. Since 26th May 1939 it has been operated by the National Park Service as the Federal Hall National Memorial. The Doric columns designed by Ithiel Town and Alexander Jackson Davies resemble those of the Parthenon in Athens and illustrate a reference towards Greek democracy. The inner dome, designed by John Frazee, recalls the Pantheon in Rome and the economic power of the Roman Empire.
