Porta Gemina o Romana

Porta Romana, also known as Porta Gemina because of its round arches, allowed the entrance to the city to people coming from Rome via Salaria Road. It has a big archaeological value. It dates back to the first century b.C. and it was built on the ruins of the ancient Picena Gate after the destruction caused by Strabone. Its structure is lateritious and of heap of stones.
An ancient town wall fell into line with the Gate. It went onto the slopes of Pia Fortress and counted five fortalices, as attested by the maps of the seventeenth century. On the side of the Gate there is a cylindrical tower of the thirteenth century, built in stones, with battlements and stringcourse jutting out of the town wall.
An inscription placed on the side remembers a De Morontis who was the head of the Commune and the Captain of People in 1314. He did his best in strengthening the city wall that showed the weaker point on that spot. On the left a medieval gate in stone ashlars is visible.
