Chambord is probably the second most famous chateau in France after Versailles, and arguably the more impressive of the two — a fantasy of towers, chimneys, and dormers rising from the flat Sologne forest. Begun in 1519 for King Francis I, the castle is square-shaped with a central keep connected to the outer wings by galleries. Inside the keep, a famous double-helix spiral staircase — widely attributed to Leonardo da Vinci — allows two people to ascend simultaneously without ever meeting.
The castle sits in the largest enclosed forest park in Europe, a national hunting reserve home to deer, wild boar, and abundant birdlife. Several footpaths through the estate are open to the public.
Top priorities for a visit: the double-helix staircase, the second-floor barrel-vaulted coffered ceilings, the rooftop terrace (the view over the estate is extraordinary), the apartments of Louis XIV, and the suite of Francis I.
