The Berlin Wall was a barrier that separate East Berlin from West Berlin. Construction began on this wall in August of 1961 and it completely cut the allied-controlled West Berlin off from East Berlin and the rest of Germany. It was rebuilt and fortified a number of times and the final wall was constructed of concrete blocks with guard towers along the perimeter. The wall was separated from the west by a large open strip of land with anti-vehicle traps and nail beds. On midnight of Saturday the 12 august 1961, the borders between east and West Berlin were closed. German troops and police began to tear up streets, telephone line, and railway lines along the border making the boarder impassable for vehicles and people alike. They also installed barbed wire fencing along the 156 kilometers (97 miles) around the three western sectors, and the 43 kilometers (27 miles) that divided West and East Berlin. Effectively overnight the West was separated from the East with no regards to citizens and businesses. It was not until the 9 November 1989 that the Berlin wall “fell.” This date does not mark the actual destruction of the wall, but rather the destruction of the ideas that caused it to be erected.
