Agios Efstratios or Saint Eustratius, colloquially Ai Stratis, anciently Halonnesus or Halonnesos, is a small Greek island in the northern Aegean Sea about southwest of Lemnos and northwest of Lesbos. The municipality has an area of 43.325 km2. Together with Lemnos and nearby islets it forms the regional unit of Lemnos, part of the Greek archipelagic region of the North Aegean.
Agios Efstratios is quiet, isolated and dry, with a population of approximately 300 people. The climate is arid, with little rainfall during the winter months and long, hot summers. The landscape is mostly rocky, with scarce and low vegetation. Locust infestation is a recurring problem. Crops are insignificant; the surrounding sea, however, is rich in fish which are fished by local fishermen. There are numerous beaches on the island such as Agios Antonios, Lemonies, Avlakia and others, most of which are reached by caique. Agios Efstratios Island is linked by boat with Limnos, Agios Konstantinos, Kymi and Kavala.
reported that, on 4 June 2009, at a two-day international conference in Athens on "Climate change and Challenges for the Future Generations" under the patronage of UNESCO, Greece's Development Minister Kostis Hatzidakis said that Agios Efstratios would soon become the country's first "green" island, entirely powered by renewable energy sources, its residents relying on solar and wind generated energy and moving around the island on bicycles and in electric cars. Hatzidakis said a €10 million project would be implemented by 2010. At the same conference Professor Philippos Tsalidis, Development Ministry General Secretary for Research and Technology, said that although Greece's energy needs currently required strategic reliance on natural gas, Aghios Efstratios, could serve as a global model for 100% reliance on RES. Agios Efstratios is included in the European Union's Natura 2000 network of nature protected areas.
Transportation
Agios Efstratios has one port, which offers year-round ferry connections to the island of Lemnos, as well to mainland Greece, namely Lavrio. The ship operating these routes is owned by Hellenic Seaways. There is also a small heliport on the main village outskirts, but it is used mostly for emergency airlift, or coast guard and military helicopters' stopover.
Agios Efstratios serves as the basis for the fictional island of Stratis in the 2013 video gameArma 3, along with its northern counterpart of Lemnos, fictionalized as "Altis", the governing body of the two islands. However, "Stratis" in Arma 3 has some critical differences from Agios Efstratios, including numerous additional military bases scattered around the island in-game, and a large airport built off artificial land into the sea south-west of the village of Agios Efstratios. In the game, it is located south of Altis, based on Lemnos. The Republic of Altis and Stratis is located just south of Malta in the game, as opposed to east of Greece.
