On the occasion of the 40th anniversary of the building of the Berlin Wall, Klaus Eschen's photo essay on his native city during the 1960s is particulary timely. The 1960s was a dramatic decade in Germany: it was a time of radical political change and social upheaval in which the traces of World War II were still evident. Those who wonder where the Berlin Wall once stood will find the answer here as Eschen preserves the memory of a place of political volatility, economic expansion, and social diversity.
