Evros river has some islets, the most important of which is "Islet A", which is near Dikea and is divided among Greece, Bulgaria and Turkey. In the middle of the islet there is the "tri-national", which is the point where the borders of the three countries meet. This is marked by a concrete triangular pyramid, one meter high, on the sides of which the three flags are painted. The islet covers an area of 340 acres, 170 of which belong to Turkey, 85 to Greece and 85 to Bulgaria.
