No other city better illustrates the upheaval in late 20th-century Europe than Berlin. For nearly 30 years it was, for all
intents and purposes, two cities. Tourists posed on the Western side of the Berlin Wall, and those who crossed the East-West
boundary at Checkpoint Charlie did so with the trepidation of travelers to another planet.
Then, in 1989, Berlin changed virtually overnight. The wall has all but vanished; Checkpoint Charlie is a museum; the No Man's
Land that lay between the two zones is now the site of a new complex of ministries, offices, stores and hotels, providing
facilities for the German parliament and government. Reunified Berlin is an exciting, restless place, reinventing itself at
a fast pace.
