Château de Chambord

As per Wikipedia - The royal Château de Chambord at Chambord, Loir-et-Cher, France, is one of the most recognizable châteaux in the world because of its very distinct French Renaissance architecture which blends traditional French medieval forms with classical Renaissance structures.

Built as a hunting residence by King François during 1519–1547 the massive château has 440 rooms, 282 fireplaces, and 84 staircases, however it was very rarely used by him. It was abandoned after King's death and after the French revolution its furnishings etc. were sold.

The château was renovated after the Second World War and is reportedly now the second most visited château in France (after Versailles). It was inspiration for the Beast's castle in the Walt Disney animated film "Beauty and the Beast".
