@taxiguy: it's an old junkyard. The authority want since more than 20 years to close it (environment etc.), but the owner is against it. They had juristic fights a lot.
The new idea (and the only chance) of the owner is, to declare it as a museum, a cultural-historic sight. So he started to mount stairways and lookouts. Also some artists have placed some installatations (like this white plastic, you can see on some pics).

Just yesterday, on a big oldtimer-market in Northern Germany, I've met the "tinhunter"-guy, and this weekend a friend from Switzerland has visited me (surely he knows that place, too), so I got the latest news from the first hands.
Martin, the "tinhunter" told me, that a few weeks ago, he has been there again to take photos of all cars there. He was the last visitor, before they begun with the art-decoration.
Philipp, the Swiss guy (also the president of the Swiss Old-Beetle-club) told me, that the owner is a bit strange (like a lot of these old junkyard-men).
He always refuses to sell cars or parts (since years Philipp tries to pick up one of the split-screen-Beetles from him). He wants to keep the place as it is - or everything will be cleared off and brought to the scrap-shredder.
A time ago, one Porsche was sold - picked up by a helicopter, because it was the only chance to reach that car.
