Byllis, founded in the 4th century B.C, is the largest ancient Illyrian city in the south of Albania. It is located on top of the hills of Mallakastra, from where beautiful panoramas of the Vjosa River and the surrounding green landscape, as well as the country’s ancient history, can be truly absorbed. The walls of Byllis were 2,200m long, enclosing 30 hectares of a plain atop a hill 524m above sea level. There were 6 gates in the city walls. Bronze coins of the city dating back to year 270 B.C prove the prosperity of Bylis in antiquity. Visitors during the visit in the The Byllis Archaeological Park can see the beautiful ruins of the theater (Parts of the theater’s forty rows of tiered seats, supporting walls and the orchestra’s pedestal can still be seen today; The Hellenistic heart of Byllis includes a theatre 16 m high, with a diameter of 78 m and a capacity of 7500 spectators); stadium (ranked as the second most well-preserved one of the country the stadium affords views of 19 stairs made of ancient stone), water depots, gymnasium, promenades, remains of former dwelling spaces and some of the most valuable Palaeo-Christian ruins in Albania (the most important Palaeo-Christian remains in Albania are constituted by the ruins of several churches constructed during the 5th century A.D.
