“ In his days the University of Paris received its first royal charters of privilege. Under him a crowd of fair buildings, conspicuous among them the cathedral of the capital, grew up in that new Gothic style that was soon to spread from the Isle of France all over the Western world. As the seat of the most famous schools north of the Alps, as the centre of the only centralised continental monarchy, and as the special haunt of the traders of Northern Gaul, Paris now took a unique place, not only among French towns, but among the cities of Western Europe. ”
