The forest of Halatte

Take a breath of fresh air and history in the forest of Halatte!

Formerly called Senlis forest, the forest of Halatte, which extends over 4300 ha, takes its name from Mount Alta (140 m), second highest point after Mont Pagnotte (220m).
With its "mountains", its tall forests of oaks and beeches, the forest of Halatte is part of the massif of the Three Forests: Halatte, Ermenonville and Chantilly.

During the Renaissance and under the Ancien Régime, rectilinear perspectives, star crossroads, crosses, tables and poles were arranged to facilitate the practice of hunting.

Are you a history buff?

It contains several vestiges of the past: standing stones ashe two Indrolles menhirs, the “Chancy Horse” or “the Horn Stone”. You will also find emblazoned terminals testifying to the division of the forest between the king and the various lords.

Did you know ?

To the west of the village of Villers St Frambourg-Ognon, in the forest, were discovered the remains of a Gallo-Roman healing temple. Small in size, the temple adopts a square plan, with a cella in the center, reserved for the cult statue. A wall enclosed the sacred enclosure (temenos).

Nearly 300 stone ex-votos depicting human beings, a few animals and anatomical fragments dated between the 1st and the 3rd centuries from this site, are exhibited to Museum of Art and Archeology of Senlis.
