Grotte du Serment

Highlight • Gorge

The Oath Cave is quite surprising, especially because the vault is made of a single rock. The letters D.F.D were engraved on the cave by Denecourt himself and mean "Last Folie Denecourt".

What immediately catches the eye are the water lilies which partly cover this 20 m diameter pond. In March, toads and frogs meet up to lay eggs. The name of this pond comes from the fact that a man named Piat, general forest guard, would have had trouble with people who had to complain about his severity in the service and who would have thrown him into the pond. This forced bath was not fatal to him, since he died at the age of 81, on August 26, 1805, leaving a large family.

This sculpture, made of concrete and iron, represents the fantastic creature from Greek mythology which gave its name to the work. 22.5 meters high, the sculpture is a project by artists Jean Tinguely and Niki de Saint Phalle, carried out between 1969 and 1994. On site, you can also discover two other works: the Face of Mirrors and the Tribute to the Deportees. Visiting all the monuments is completely free.

Standing in the heart of the Gâtinais, the Courances estate extends over 75 hectares and includes a magnificent 17th century castle as well as its park and vegetable garden. Closed during the winter, it opens its doors the rest of the year for fun visits. If you're not pressed for time, don't hesitate to drop by.
