Within the Roman empire Aquileia was a major trading centre connecting the Mediterranean to Central Europe. The city’s wealth and status were reflected in its magnificent public buildings and private residences, many of which survive as archaeological remains.
The most striking of these ancient treasures are those of the port installations, a long row of warehouses and quays that stretch along the bank of the river.
The dominant feature of Aquileia is the Basilica, erected, primarily, in the early-Christian period. The imposing mosaic floor dates to the Theodorian church built at the beginning of the IV century and rebuilt between the 11th and 14th century according to the Romanesque and Gothic style.
