The small Greek island of Dokos had a recorded population of just 18 people in the latest census – however 85-year-old Irini Douskou is the only person who is known to live there permanently.
The few monks and shepherds listed on the census come and go, but she refuses to abandon her birthplace despite the difficulties of life there.
Near Hydra, the entire island has been characterised as an archaeological zone and nothing new can be constructed there.
Ms Dousko, who lives an isolated life, was recently featured on CNN. She told the crew that it is the island that keeps her alive.
Life is a little easier for the old woman during the summer months, as day-trippers flood the area. Occasionally Ms Dousko leaves to visit Hydra where her son and daughter live however she refuses to abandon it for too long.
