Château de Chambord
Château de Chambord is a distinctive French renaissance castle built for King Francis I in the 16th century. It was originally designed to serve as a hunting lodge. The current custodians claim the architect was "probably" Leonardo DaVinci (who happened to live down the road for a bit) based on the fact that a few sketches of his contain a staircase not dissimilar to the one found in the château. Other sources claim the designer was actually Domenico da Cortona, an Italian architect brought to France by Charles VIII in 1495.
