Considering the Steigenberger Duisburger Hof in Düsseldorf?
A VT member wrote the following comment about visiting Düsseldorf:
Bizzare Clock... by steventilly
There is a bizarre clock on the TV tower. It's a bit of a game to try to get visitors to figure out the time by looking at the tower. Of course I got it straight away, but apparently some people can take ages to figure it out.
It's not very clear from this pic, but the clock is a series of lights on the side of the tower that faces the Altstadt.
