Tidevandsø
En tidevandsø er et stykke land, der er forbundet til fastlandet ved en naturlig eller menneskeskabt dæmning eller dige, der er oven vande ved lavvande, men oversvømmet ved højvande. På grund af mystikken ved tidevandsøer har mange været stedet for religiøse steder, som eksempelvis Mont Saint-Michel med Benediktinerordenens kloster. Tidevandsøer er også ofte blevet brugt til fæstninger på grund af deres naturligt forskansning.

Cramond Island and causeway (submerged in this picture, pylons visible). Photo taken from a plane, minutes before landing at Edinburgh Airport. I cropped out parts of the photo where the landing gear etc was showing, but I felt I had to leave in the top of the photo where a part of the wing is present, because I wanted the horizon and the other side of the firth to remain visible.
