In this square, you will find a clever series of grey granite platforms and monuments with brick façades: the Chamber of Commerce and Industry, by the architect Deslandes, with the look of an ocean liner and topped by transparent tubing enabling light to penetrate inside; the town hall by J. Lévy, with its lofty glass ceiling, in front of which water jet fountains spout forth; and the extraordinary cylindrical cathedral designed by Mario Botta.
