From a little-known hill to a hidden tunnel. Sofka introduces the series and herself: a British writer and one-time anthropologist, she’s an adopted Greek with a Russian name. We visit an unfamiliar hill – the Tourkovounia. Former US diplomat and archaeologist Brady Kiesling gives a sense of Athens’ geography - an urban sprawl surrounded by mountains and sea. Sofka goes down below for a taste of the remarkable riches lying underground and pays her respects to the city’s most famous skeleton. George Sachinis - a community artist and Water Board employee, leads us inside an aqueduct tunnel built by the Emperor Hadrian, which is still functioning after 2,000 years.
