European Cities: result of very long histories
Complex street patterns - prior to automobile, weird angles
Plazas and Squares - from Greek, Roman, Medieval Low skylines - many built before elevators, others
required cathedral or monument to be highest structure
Lively downtowns - center of social life, not just office work
Neighborhood stability - Europeans moved less frequently than we do.
Scars of War - many wars , many cities originally defensive
Symbolism - gothic cathedrals, palaces, and castles
