Civitavecchia

Civitavecchia is a town and comune of the province of Rome in the central Italian region of Latium. A sea port on the Tyrrhenian Sea, it is located 80 kilometers west-north-west of Rome, across the Mignone river. The harbor is formed by two moles and a breakwater, on which is a lighthouse.
Civitavecchia means "ancient town".

The modern city was built over a pre-existing Etruscan settlement.
The harbor was constructed by the Emperor Trajan at the beginning of the 2nd century. The first occurrence of the name Centum Cellae is from a letter by Pliny the Younger (AD 107). The origin of the name is disputed: it has been suggested that it could refer to the centum ("hundred") halls of the villa of the emperor.
In the high Middle Ages, Centumcellae was a Byzantine stronghold. Captured by the Saracens in 828, it was later acquired by the Papal States.
The place became a free port under Pope Innocent XII in 1696. The main port of Rome in modern era, it was occupied by the French in 1849. On April 16, 1859 the Rome and Civitavecchia Rail Road was opened for service. The Papal troops opened the gates of the fortress to the Italian general Nino Bixio in 1870.
During World War II, Civitavecchia was severely damaged by Allied bombings, which caused several civilian casualties.
