In the eastern suburb of Aquinum is the honorary arch so-called ” di Marcantonio”. The attribution of this, very suggestive, draws its origins by Cicero (Cic. Philipp., II, 41, 105-106). The monument is one of the oldest examples of honorary arch known in Italy. Built in blocks of local travertine, the Arch missing of the entire top. The lower part of the monument is not visible, because is submerged by a water course.
The elegant shape of the arc “Marcantonio” have always aroused interest: in the Renaissance is designed and integrated with hypothetical reconstructions, by Antonio and Giuliano da Sangallo, Sallustio Peruzzi, Giovannantonio Dosio.
The construction of the monument is dated to around the years 41-40 BC
