I loved visiting the glass dome of the Reichstag in Berlin.
The whole construction is simply ingenious and it serves a 360° view over all of Berlin.
Getting in there is kinda like trying to enter Fort Knox – having to sign-up and be ‘approved of’ days in advance, as well as strict security checks when entering (well, it is a governmental building after all, so no surprise there really ;)).
However, it is all more than worth the effort! 🙂
