The Malborghetto Arch is a tetrapylon, whose origin dates back to the turn of the 3rd and 4th century. The property is located on the ninth kilometer of ancient Via Flaminia. This place was to witness the famous vision of Emperor Constantine before the battle at the Mulwijski Bridge - 'In Hoc Signo Vinces'. The characteristic building was erected to celebrate this victorious fight with Maxentius. The building is now a small archaeological museum.
The first excavations undertaken by Fritz Töbelmann were stopped due to the outbreak of World War I. Another work began in the 80 'prof. Gaetano Messineo. Coins he found from the first half Fourth century were the main argument for embedding the building in the time of Constantine. Further research confirmed the possibility of a military camp appearing here.
Over the years, the arch served as a small church and then a defensive structure. The building was also the seat of a horse post office and an element of a rural homestead.
