  • From 1961 to 1989 the Berlin Wall was the physical manifestation of the Iron Curtain, separating West Berlin from the surrounding German Democratic Republic (East Germany). Originally erected as a series of barriers and barbed wire, the proper wall was built just inside East Germany territory with a large cleared space before the wall known as the "death strip." This year marks the 30th year since the removal of the wall and the reunification of Berlin. <br><br> The construction site of the Berlin Wall is pictured on June 6, 1961.

  • President Ronald Reagan, commemorating the 750th anniversary of Berlin, addresses on June 12, 1987, the people of West Berlin at the base of the Brandenburg Gate, near the Berlin wall. Due to the amplification system being used, the President's words could also be heard on the Eastern (Communist-controlled) side of the wall. "Tear down this wall!" was the famous command from President Reagan to Soviet leader Mikhail Gorbachev to destroy the Berlin Wall. The address Reagan delivered that day is considered by many to have affirmed the beginning of the end of the Cold War.

  • The Berlin Wall in front of Branderburg Gate on the night of Nov. 9, 1989. Thousands of celebrants climbed on the Wall as news spread rapidly that the East German Government would now start granting exit visas to anyone who wanted to go to the West. The announcement was misinterpreted as meaning the border was now open and East German border guards were unable to stop the rush of people to the Wall. Within hours people were smashing sections of the Wall with their own hand tools and these first cracks in the Wall led to the complete opening of the border within days.
