Situation
Aquileia lies in central Italy - west of the place where the River Isonzo, flowing down from the Alps, flows into the Adriatic.
History
Founded by the Romans in 181 B.C. as a defensive post against the Celts, Aquileia became one of the great
cities of ancient Italy, a major trading center in the Gulf of Trieste and from the sixth century the seat of a Patriarch. Later it lost its importance.
The cathedral and archeological remains in the town of Aquileia were designated a World Heritage Site by UNESCO in 1998.
