With the recent completion of several new stations and tunnels, the Athens underground metro expansion and the development of the Thessaloniki Metro system are on a set course to completion in Greece. The construction of a direct connection between the Athens airport and the Piraeus harbour, as well as the development of Thessaloniki’s first metro line, are underway, and images by photographer Pygmalion Karatzas show the new underground infrastructure coming together in the two Greek cities.
