The Arcadian Way or Harbour Street and the Great Theatre in the background. The Arcadiane was over 500 metres long and 11 metres wide. In antiquity it led from the Great theatre to the harbour (now silted up). Originally built during the Hellenistic period, the street was restored during the reign of Roman Emperor Arcadius (395-408 AD) whom the street was then named after. It was laid with marble and lined with covered porticoes on each side and even street lighting was provided by a number of lamps.
