Via Egnatia, a via publica laid out around the mid-2nd century bce by Cnaeus Egnatius, in part on top of older roads. It continued the Via Appia, leading from the Adriatic ports of Dyrrhachion (Durres) and Apollonia (in modern Albania) through Thessalonica and Philippi to Constantinople/Byzantium (Istanbul). It was thus the most important land route connecting Rome and the Balkans, Asia Minor, and the Levant; it continued to play a significant role into the early Middle Ages.
