This picture is taken from a very interesting location.
It's located nearby Nummer En ( Number One), a small village along the Western Scheldt, not far from Breskens.
Outside the levee/dike a footway/cyclingtrack is constructed, when it's springtide this track is inundated by the seawater!
When it's a normal high tide, you walk or cycle almost on sealevel!
The picture of this Turnstone is taken from the footway, when the water was somewhere half between high and low tide.
