The confluence of strangers in a single place and under a single law, there to live peacefully side by side, joined by social networks, economic cooperation, and friendly competition through sports and festivals, is among the most remarkable achievements of our species, responsible for most of the great cultural, political, and religious innovations of our civilization.

Nothing is more precious in the Western heritage, therefore, than the cities of Europe, recording the triumph of civilized humanity not only in their orderly streets, majestic facades, and public monuments, but also in their smallest architectural details and the intricate play of light on their cornices and apertures.

The American who leaves the routes prescribed by the Ministries of Tourism will quickly see that Paris is miraculous in no small measure because modern architects have not been able to get their hands on it. Elsewhere, European cities are going the way of cities in America: high-rise offices in the center, surrounded first by a ring of lawless dereliction, and then by the suburbs, to which those who work in the city flee at the end of the day.

Admittedly, nothing in Europe compares with the vandalism that modernists have wreaked on Buffalo, Tampa, or Minneapolis (to take three examples of American cities that cause me particular pain). Nevertheless, the same moral disaster is beginning to afflict us—the disaster of cities in which no one wishes to live, where public spaces are vandalized and private spaces boarded up.

Until recently, European architects have either connived at the evisceration of our cities or actively promoted it. Relying on the spurious rhetoric of Le Corbusier and Walter Gropius, they endorsed the totalitarian projects of the political elite, whose goal after the war was not to restore the cities but to clear away the “slums.” By “slums,” they meant the harmonious classical streets of affordable houses, seeded with local industries, corner shops, schools, and places of worship, that had made it possible for real communities to flourish in the center of our towns.
