Napoleon's Oak. The name seems to derive from the fact that it was used by French soldiers to tie their horses to (which is at least plausible, considering that the tree is certainly centuries old). According to another legend, less plausible, Napoleon Bonaparte himself stopped to rest in its shade (but in the last century throughout Europe there was an inflation of houses, hotels, castles and convents in which it was claimed that Napoleon would have stopped to sleep... a number so high as to be unlikely, and probably the result above all only of popular rumours).
