The three following photos are from a visit to a town that used to be...not. On this map, which is from Roman times, it would be in the far left corner just inside the red line, which represents where the coast is now. Compare that to the previous map which is the same area! Each of the little black dots on the islands is a town, and we drive to our mission meetings straight up the left third of this area. Monks started draining this area about 650 AD, and there are still dikes that keep the sea out.
