Aquileia, with its immense archaeological site and its Patriarchal Basilica, is an artistic and historical treasure trove. Located in Friuli Venezia Giulia (Udine Province), it was added to Italy’s register of UNESCO World Heritage Sites in 1998. It was also one of the largest and richest Mediterranean cities within the Roman Empire, and eventually was made seat of the Ecumenical Patriarchate that lasted until 1751. Thus, Aquileia became a dominant hub of the Christian world for Central Europe from the Middle Ages to the 18th Century. The archaeological excavations have not brought to light everything regarding the the Roman Era city; nevertheless those that have been found are certainly one of the best-preserved testimonies to Ancient Rome’s grandeur.
