20th December 1963 - Berlin Wall opened for first time

More than two years after the Berlin Wall was constructed by East Germany to prevent its citizens from fleeing its communist regime, nearly 4,000 West Berliners are allowed to cross into East Berlin to visit relatives. Under an agreement reached between East and West Berlin, over 170,000 passes were eventually issued to West Berlin citizens, each pass allowing a one-day visit to communist East Berlin.
