Hotel de Sully is located at 62 Rue St.-Antoine 75004. On the left are dormer windows and statues of the four seasons and sphinxes, in its courtyard.

This fine 17th-century mansion was built in 1624 for a notorious gambler, Petit Thomas, who lost his whole fortune in one night. The Duc de Sully, Henri IV's chief minister, purchased the house in 1634 and added some of the interior decoration as well as the Petit Sully orangery in the gardens. It is now the head office of the Caisse Nationale des Monuments Historiques.

The exterior of the hotel has an imposing late-Renaissance facade. Inside there is a large and beautifully proportioned courtyard with attractive pediments.
