Potsdamerplatz has been described as epitomising the new face of Berlin - and with good reason. A generation ago this sector of the city was a wasteland, a patch of heavily fortified no-man's land between East and West. The collapse of the East German State meant that not only did the State-controlled economy end rather abruptly but it also gifted German capitalism with a rich supply of development land in the heart of the city.
What has replaced the barbed wire, and attack dogs is office blocks, shopping centres, European head-offices of Japanese multi-nationals and bustling outdoor markets.
