Marble Stairs - Chateau Chambord&lt;br /&gt;
&lt;br /&gt;
Day 39 - May 19 (cont.) - We ducked in the castle door just as another wave of rain hit, and chose the unguided tour so we could explore the interior at our own pace. We wandered about for two hours, exploring the towers, walking the parapets, and admiring a fine collection of sporting guns, hunting trophies and machinery. One major feature was a double spiral marble staircase, designed by Leonardo di Vinci.
