The Amphitheatre of Durrës is one of the largest Roman amphitheatres in the Balkans, with an estimated original capacity of 15,000 to 20,000 spectators. Built in the 2nd century AD when Dyrrachium was an important Roman port city, it was discovered only in the 1960s and is still only partially excavated — a remarkable amount of it lies beneath the surrounding neighbourhood.
What has been uncovered is open to walk through, and the experience is genuinely atmospheric: you descend into the arena, walk the tunnels beneath the seating banks, and examine the early Christian mosaics in the converted vaulted passageway. The mosaics — saints in a Byzantine style — are among the finest early Christian artworks in Albania and the reason the site is protected as a UNESCO candidate. Entry is cheap and the site is usually uncrowded.
