Considering the Hotel Villa Kastania in Berlin?

Fernsehturm Tower by bpwillet
This 60's era tower was used as a TV tower. Built in the height of the Cold War it was meant to send out a message to the West. You can visit the top of the tower which has a revolving observatory. On a clear day, they say you can see for almost 40km. There is a restaurant up top as well. This tower also stands as a good reference point in Berlin, and one of Europe's tallest structures.
