For swap with my Missing WHS or rare countries I haven't yet.

* The one with no name on is Azay-le-Rideau *

Loire Valley WHS is not only castles and not all "Loire Valley" tourist castles are on the official UNESCO list (Cheverny, Angers, Semblançay are not for example) but Chambord, Chinon which are not on the Loire borders are on it .... So I propose ONLY official ones !

Loire Valley WHS is churches, abbeys, towns, small towns with dikes along the Loire too. It is the whole Loire Valley with its flooding risk and life adaptation, biodiversity, history !!!
