The principal sight of Warsaw is Warsaw. There is nothing here to compare with San Marco in Venice or the Tower of London, because the city itself is the major attraction. Warsaw was destroyed in the literal sense like Carthage, leveled to the ground, by the German fury in World War II. The urban environment is vastly different from the rural, for in it is always a concentration of services and varied goods. It is a meeting place and melting pot, both a refuge for people and ideas and also a reservoir of new ideas and venturesome populations. The word "city" once suggested "civility" and those characteristics of culture and politeness which attend that term. In a generic sense, the "city" referred to the financial and commercial district of greater London. In ways partially symbolic and partially real, the nexus between the cultural and commercial cores of the city remained in a healthy condition.
