Chateau de Rentilly is located in the east suburb of Paris, 30 minutes away.
In a nice park, you can discover a masterpiece of the artist Xavier Veilhan, he covered the castle with mirrors ! The architecture becomes spectacular.
You enter La Fidelity and will find a very classic Parisian Brasserie, probably almost empty. Maybe one or two people at the bar. In the middle of this place you will find the stairs that go down to the cave. Have fun!
