The appearance of a hastily-constructed barbed wire entanglement through the heart of Berlin during the night of 12-13 August 1961 was both dramatic and unexpected. This book reveals the strange and chilling story of how the initial barrier system was conceived, then extended, adapted and strengthened over 30 years.
