The château of Chenonceaux straddles the Cher River forming a sort of bridge.  During WW-II, the Cher was the 'frontier' between Nazi-occupied France and Free France.  Chenonceaux was used many times for prisoner exchanges.

This, like most of the Loire châteaux, dates from the period just before the French Revolution.  The interior is, therefore, high Baroque: overblown, overdone, larger-than-life portraits of aristocrats in powdered wigs, cherubs by the millions, and figures from Greek and Roman mythology, all in gilded wood frames that look like an attack by triffids.  'Price' was clearly no object because the people paying the bills considered mere money not worth worrying about.  Besides, there's more where that came from, isn't there?
