Greater Tonb Martyrs Island at Tehran, under construction
Tehran's District 22 Parks and Lake development includes an artificial lake, named Persian Gulf Martyrs Lake (aka Chitgar Lake), and three artificial islands: Abu Musa Martyrs Island with a span of 1.4 hectares, Greater Tonb Martyrs Island with a span of one hectare and Lesser Tonb Martyrs Island with a span of half a hectare. Above photo depicts construction development at the eastern part of Greater Tonb Martyrs Island.

What appears to be Hawksbill sea turtles (Eretmochelys imbricata), introduced into a Persian Gulf Martyrs Lake planned ecosystem. (Not sure how they'll fare with all the recreational watercraft activity on the urban artificial lake.)
