Located in the province of Rome, Civitavecchia is an active port on the coast of Lazio, second in Europe for number of cruise passengers, embarking to the most famous tourist destinations in the Mediterranean. Mentioned for the first time in Pliny the Younger in 107 AD as "Centum Cellai, the discovery of small rustic buildings in the area attest the presence of populations of Etruscan origins, experts merchants who, through the exploitation of the mines of the Tolfa mountains, intensified trade with the neighboring populations. A large increase in the economic and social growth of the city and its port was recorded when new commercial needs arose for Rome, as Ostia and the ports of the South were insufficient: the works were assigned to Apollodorus of Damascus in 102 A.D. After the fall of the Roman Empire, Civitavecchia first passed under the Byzantine rule and then under the direct control of the Papal States. Reduced to ruins, during the Saracen raids of 813 and 828, the survivors were forced to shelter in the inland areas, less vulnerable to pirate attacks. The current name was registered only after year 1000, when the old residents of "Centumcellae" returned to live in the "Civitas vetula". The State of the Church strove to strengthen the defenses of the city and entrusted to Antonio da Sangallo the building of fortified walls, ordering the construction of towers, defensive systems and a permanent fleet in order to make Civitavecchia a bulwark against the incursions Saracen, thus becoming again the port of Rome.
