Wikipedia:"The Tränenpalast (English: Palace of Tears) is the Berlin colloquialism for the former border crossing station at the Berlin Friedrichstrasse railway station, where East Germans said goodbye to their families and visitors going back to West Germany. From 1962 to 1989, the "Tränenpalast" was the central terminal for travellers between East and West Germany. The building was used only for westbound border crossings, with separate checkpoints for citizens of West Berlin, citizens of West Germany, foreigners, diplomats, transit travellers and East German citizens.The expression "Tränenpalast" derives from the tearful goodbyes that took place in front of the building, where western visitors of the divided city had to say farewell to their East German relatives that were not permitted to travel to the Western part of Berlin"
