If your trip to Jargeau is all booked but your travel itinerary is looking a little empty, let us give you a helping hand.Close to the city center, Château de Sully-sur-Loire is one sight you might like to put on your must-see list. If you still have some space on that travel itinerary, Oratoire de Germigny-des-Prés and Abbaye de Fleury will keep you busy too.
