La Tour Saint Antoine from the terrace of the sous-préfecture (that is to say, from the terrace below the Agnès Sorel tower of the Logis Royal, which used to be the sub-prefectural office). I think you could just about get this view without having to step into fresh air, but I think you might have to lean to the right quite a lot, and the terrace is nowhere near as extensive as the painting shows.
The Tour Saint Antoine taken from the artist's garden ie from the other side of the citadel, but looking in the same direction.museum dedicated to his memory and works. The house and garden are charming, and very thoughtfully presented. The staff clearly love the place and are delighted when foreign tourists take the time to visit. The museum is free and the views from the garden spectacular as the house is on the citadel, right next to the medieval gateway (known as the Porte Royale) .

The Chateau of Chenonceau. I doubt if you could get this view even if you were on the river. It is supposedly from the river bank.
