Paris is a big city, in the sense that London and New York are big cities, and that Rome is a village, Los Angeles a collection of villages and Zürich a backwater.
A reckless friend defines a big city as a place where there are blacks, tall buildings and you can stay up all night. By that definition Paris is deficient in tall buildings; although President Pompidou had a scheme in the sixties and early seventies to fill Paris with skyscrapers, he succeeded only in marring the historic skyline with the faulty towers of a branch university, Paris VII at Jussieu (which was recently closed because it was copiously insulated with asbestos), the appalling Tour Montparnasse—and the bleak wasteland of the office district, La Défense.
