The Sylphes Pond

Highlight • Lake

Much less known than the other 2 ponds of Carnelle and much smaller too, this pond remains very pretty with its island of water lilies.

Lac Bleu is one of the two bodies of water in the Carnelle forest. On sunny days, its name takes on its full meaning. But there is another reason for the name of this lake from ancient quarries. The rock at the bottom is a mixture of gypsum and marl. The color is changing due to algae, but originally it is deep blue. Around the lake, one can appreciate oaks, beeches and chestnuts. A feast for the eye!

The Château-pital of Saint-Martin-du-Tertre

Highlight • Castle

A beautiful castle, located at the bottom of St Martin du Tertre, it has long served as a hospital. It seems that this is no longer the case. The hospital would be installed on the grounds of the domain a little more to its left.

Tour du Plumet

Highlight • Monument

The Tour du Plumet was built in 1863, commissioned by Baron Joseph Louis Léopold Double, a wealthy aristocrat. It was a meeting point for hunting. This tower was part of a larger ensemble which was the baron's home. He collected many pieces of art there. But it is impossible to escape the translatio imperii or "transfer of power". This building is the only survivor of the entire construction.
