This obelisk was built in 1811 to commemorate the birth of the son of Napoleon I and Marie-Louise of Austria, made king of Rome by his father to defy Pope Pius VII. Why here and by whom? We don't know anything about it. This tribute was perhaps paid to Napoleon for the relaunch of healthy management of the Halatte forest after a period of abandonment following the revolution of 1789. In any case, he met his future wife Marie-Louise d'Halatte. Austria, nearby, at the castle of Compiègne where he installed his son the king of Rome.

The royal abbey of Moncel was built in the 14th century by Philippe le Bel, next to an old manor which the king transformed into a royal residence at the same time. Without a doubt, a major place of French heritage!
