The outstanding staircase in France’s Chambord Castle
Chambord’s château is one of the most unique Renaissance structures to be seen and visited today. Leonardo Da Vinci, the Italian polymath and painter, designed it in 1516. It was placed in the keep’s heart, where four large rooms converge, and it is made up of twinned helical ramps that twist one on top of the other.
The so-called “double helix” staircase serves the building’s main floors up to the crowning terraces, which are topped off by the castle’s tallest tower, the lantern tower. This looks like the perfect place for a sword fighting scene in Swashbuckler, the romantic adventure film.
