The Arch of Augustus in Fano (in the Province of Pesaro and Urbino) is a city gate in the form of a triumphal arch with three vaults. It is the entrance to the city by the via Flaminia, which became the inside of the wall of the decumanus maximus. It is one of the symbols of the city.

In the Roman period it was the principal 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.

It is presumed that at least two other (now lost) gates existed in Fanum Fortunae, one to the south and the other near the sea.

Constructed at the point at which the Via Flaminia met the decumanus maximus of the city, the monument is dated to AD 9 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. CAESAR DIVI F. AVGVSTVS PONTIFEX MAXIMVS COS. XIII TRIBVNICIA POTESTATE XXXII IMP. XXVI PATER PATRIAE MVRVM 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.

The arch was later rededicated by the Emperor Constantine I with a new inscription on the attic which is now lost, but the earlier inscription was not erased.^[1]

In 1463, during the siege of the city in order to expel its lord Sigismondo Pandolfo Malatesta, the artillery of Federico da Montefeltro, destroyed the attic of the monument. The fallen fragments were reused in the construction of the adjacent church and loggia of Saint Michael. The original appearance of the gate is recorded in the Renaissance bass relief carved on one side of the facade of the church.

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. The whole monument has many stylistic similarities with the Augustan gates of Spello, Aosta and particularly with Authon in Provence.
