Can tell you by experience, it is so difficult to get access to cool places (you all know). Had to try hard to find the door open after several attempts (building is closed due to renovations). But fortunately someone forgot to lock it and so I sneaked in and went into the basement.
This is the fire staircase of the engineering department of the technical university in Munich.The stuff hanging down from the ceiling are lamps (maybe I will get an other chance to get in when they are lit)
Wishing you a wonderful Friday with perfect light.
