A part of the Berlin Wall features a portrait of former West German Foreign Minister Hans-Dietrich Genscher, covered with the Czech flag on one side and some historical Berlin landmarks on the other.

Genscher played a key role in the fall of communist regimes in Central Europe when, in September 1989, he announced from the balcony of the West German embassy in Prague to thousands of East German refugees that they were allowed to travel to West Germany.
