Thanks Iceflower & Polyesco.
The Wadden Sea is a protected area, very rich in birdlife and for being the home of many mollusks, oysters and what not. It stretches from Southern Jutland, down along the German coast and across the Netherlands.
It's also a favorite tourists attraction - but the tide claim some every year! People think the sea is far away, but all of a sudden the water has caught up with you - and it's still a long way to dry ground...
The elderly gentleman seen close to our Marie is the Minister for Culture, Bertel Haarder, also less reverently known as Bertel Bims = Bertel Nutter.
