France is divided, basically, into the north, where tuiles plates were traditional roof covering tiles, and the south, where tuiles romaines are found. There is a line just south of Chalon sur Saone where you can see this change quite clearly, and you know you have officially entered le sud, even though the Mediterranean is still hundreds of miles away. I always stop for a glass of wine in a café when I pass this point. Roofs in the north, with their flat tiles, tend to be steeply pitched, whereas in the south the pitch is much more gentle.
