A cool château!

On the eastern side of Paris there is a massive fortress with an impressive donjon called Le Château de Vincennes. It may not be as big and prestigious as the one of Versailles, but it's definitely worth a visit (it's easy to get there by metro). At the origin - in 1150! - it was just a simple hunting lodge (built for Louis the VIIth) and then it was turned into a castle over the centuries - including a large moat in which several people (such as spy Mata Hari, Duke of Enghien and Nazi hostages) were executed. The photo I took last night shows the main entrance door (you can have a global look of the Château lay out on the official site).
