Considering the Hotel Excelsior Duesseldorf in Düsseldorf?

Nessy by IceBear7
Our Nessy is not really a piece of art, but it has something to do with air ventilation. Nessy can blow up to 70.000 cubic meters air per hour into the gully below to provide the gully workers with fresh air.
It's located at the entrance of Volksgarten.
(more "arty" pictures coming in a travelogue!)
