Just come back from a glorious week on Lesvos. Sand, sea and ouzo. But also a tank, obviously set up as a fixed gun, on the outskirts of Sigri, a village at the western tip of the island. It's in a sort of pit, surrounded by wriggly tin, with a stone wall on two sides, leaving a clear field of fire over about 90 degrees, and it was obviously put there to make life unpleasant for anyone approaching the harbour. Clearly been there a fair while. Engine and everything else removable long since removed. Anyone any ideas what it could be? Apologies for picture quality - pics taken on phone.
