After the initial opening of the Berlin Wall on 9 November 1989, Potsdamer Platz became one of the earliest locations where the Wall was "breached" to create a new border crossing between East and West Berlin.
On 21 July 1990, ex-Pink Floyd member Roger Waters staged a gigantic charity concert of his former band's rock extravaganza The Wall to commemorate the end of the division between East and West Germany.
