Two Loire Valley chateaux today, about an hour drive east from Chinon: the Chateau de Chenonceau near the small village of Chenonceaux, and the Chateau du Clos Lucé in Amboise. Both are notable, but for quite different reasons. Chenonceau is one of most famous chateaux in France, because of its size, its location spanning the River Cher, its ornate elegance; and also because, for part of its long history, it was the source of contention between King Henry II's queen and his mistress. (See Wikipedia).

The Chateau du Clos Lucé is notable because Leonardo da Vinci spent the last three years of his life there (1516–1518) as the guest of Francis I, who gave him the small chateau, connected to the royal Chateau d'Amboise, as recognition of his stature as an artist and his utility as a military engineer. The exhibits in Clos Lucé largely focus on his inventions, but reproductions of the three paintings he brought to France from Italy are also prominently displayed.
