Upon first viewing WARSAW, visitors will recoil from its bleak postwar architecture. But after further introspection, you will be amazed and awed when you consider that two thirds of its population was killed and eighty percent of the city itself was reduced to ashes and rubble by Hitler during World War II. The meticulous task of rebuilding the city took ten long years. Warsaw is rich in museums and sights and the Varsovians are immensely proud of their history of resistance to oppression. The busy Stare Miasto or Old Town is a good place to start the exploration. The Royal Castle, St John's Cathedral and Old Town Square are excellent examples of the city's massive reconstruction.
