A medieval fortress, wrecked in 1617 and rebuilt from 1857 by Viollet-le-Duc for Napoleon III as a storybook castle.
Kids cross the bridges into the courtyard, then go down a lit staircase to the cellars, where about 100 plaster effigies of French kings and queens lie under shifting lights and whispered poems. A 5-hectare wooded park wraps around the walls, with cannonballs still stuck in one tower.
