The excavation of the foundations of the Roman town are still a work in progress, but the forum with its marble columns is the most obvious remnant. Of greater importance are the 4th century floor and walls of the Basilica, contained within a building only 1000 years old. The ancient mosaics and frescoes are in pristine condition and well displayed.
I reached Aquileia from Venice by travelling by train to Cervignano, and taking the Grado bus from there to the Archaeological Museum in Aquileia.
