Germany's largest beach - as far as I know - is in St. Peter - Ording at the north sea. The tides are rising far over the beach at normal times already, since the sand is so flat. Storm tides rise even further so the setup of the beach is interesting:
To provide people on the beach with restaurant, ice cream stands and facilities there are houses far out beyond the dunes and coast line. But those houses would be in danger of constantly floding and being washed away. So they rise the houses and platforms on poles. This adds to the special look of this beach. I came here since my childhood and I will come back again and again.
This is a scene in sunset of October 2010 when we spend a week in St. Peter with friends.
