Millau sits in the valley of the Tarn, a pleasant town in the Aveyron département that was long known for two things: leather glove production and appalling traffic jams on the route south. The second problem was solved spectacularly in 2004 with the opening of the Millau Viaduct — the world's tallest bridge, designed by Norman Foster, its slender cable-stayed pylons rising over 340 metres above the valley floor. It is as much a work of art as a feat of engineering, and worth seeing from below as well as driving across.
The town itself is agreeable without being a major destination. The old centre has some attractive squares, the weekly market is good, and the Musée de Millau covers the local trades of leather and Roman pottery. The surrounding Grands Causses — vast limestone plateaus cut by deep gorges — offer excellent hiking, climbing, and canoeing on the Tarn. The Gorges du Tarn and nearby gorges of the Dourbie and Jonte are spectacular, and the strange dolomite city of the Chaos de Montpellier-le-Vieux is twenty minutes east. The Roman pottery site of La Graufesenque is a short walk from the centre, and Roquefort-sur-Soulzon, where the famous cheese is aged in natural caves, is just a short drive south.
