Arch of Augustus
it was the principle gate of Colonia Julia Fanestris, a colonia established in the town of Fanum Fortunae (temple of Fortuna) by the Roman architect Vitruvius at the command of the Emperor Augustus, in commemoration of the victory over the Carthaginian general Hasdrubal Barca in the Battle of Metauro during the Second Punic War.
Constructed at the point at which the via Flaminia met the decumanus maximus of the city, the monument is dated to 9 CE by means of an inscription located on the frieze, with large characters carved in the rock which were once gilded in bronze. The inscription reports:
IMP. CESAR DIVI F. AVGVSTVS PONTIFEX MAXIMVS COS. XIII TRIBVNICIA POTESTATE XXXII IMP. XXVI PATER PATRIAE MURVM DEDIT
Imperator Caesar Augustus son of a god, Pontifex Maximus, Consul 13 times, recipient of tribunician power 32 times, acclaimed imperator 26 times, father of his country donated this wall.
Faced with opus quadratum from blocks of Istrian stone, the monument consists of two minor lateral arches and a larger central arch: the keystone of the latter is decorated with an image of an animal which is no longer recognisable but which most probably depicted an elephant. The main body, still well preserved, supported a large attic which is now lost, with a Corinthian pseudo-portico, in which there were seven arched windows separated by eight pseudo-columns.
