Hello all.
I think that this old tower is a good choice for this challenge.

The tower has almost 100 years of history. It was there in 1945 (most survived part of it) and has been working as a dispatchers tower for main Munich airport till 1982.

Now the tower belongs to BrainLab and has an entertainment function: showroom and corporative events.

I tend to leave things that they are now, but make a little reconstruction and add some new processes, that somehow resemble its glorious past.
Photos were taken from BrainLab and archives.
Anna.
