Immerse yourself in Antiquity...
At the Pergamon Museum I loved the electronic device which commented in either abbreviated or extended format , on all the exhibits stretching over numerous halls of full scale original temples, friezes and streets/ sections of palaces, from several important civilizations in the ancient world, including greek, roman, assyrian, babylonian, egyptian and islamic art.
One needs at least half a day to even walk through all the exhibits and experience some highlights, with fitting background commentary and music provided on demand from the portable device provided. This was the highlight of my stay in Berlin, apart from the Holocaust Monument behind the Brandenburger Tor (gate), which was even more moving.
