Little remains of Tours's own château—one of France's finest cathedrals more than compensates—but the city serves as the transportation hub for the Loire Valley. Trains from Tours (and from its adjacent terminal at St-Pierre-de-Corps) run along the river in both directions, and regular bus services radiate from here; in addition, the city is the starting point for organized bus excursions (many with English-speaking guides). The town has mushroomed into a city of a quarter of a million inhabitants, with an ugly modern sprawl of factories, high-rise blocks, and overhead expressway junctions cluttering up the outskirts. But the timber-frame houses in Le Vieux Tours (Old Tours) and the attractive medieval center around place Plumereau were smartly restored after extensive damage in World War II.
