Two US presidents made landmark visits to the Berlin Wall during the Cold War: John F. Kennedy in 1963 and Ronald Reagan in 1987. Both delivered speeches that became defining moments of the era.

The Berlin Airlift was one of the most ambitious logistics operations in history – the Western Allies’ response to the Soviet Berlin Blockade of 1948–1949, in which they flew all supplies into West Berlin by air for nearly a year.

At least 140 people are confirmed to have died at the Berlin Wall between 1961 and 1989, according to research by the Berlin Wall Memorial and the Centre for Contemporary History Potsdam.

The Berlin Blockade occurred between 24 June 1948 and 12 May 1949.

The Death Strip (Todesstreifen) was the heavily fortified no-man’s-land between the two parallel walls that made up the Berlin Wall – the outer wall facing West Berlin and the inner wall on the East Berlin side.

The Berlin Wall was built to stop the exodus of East Berliners fleeing the communist regime by escaping to West Berlin.

The Berlin Wall stretched for 155km (96 miles) around the entire perimeter of West Berlin.

The Berlin Wall fell on 9 November 1989.
