École royale du génie de Mézières

The École royale du génie de Mézières (Royal Engineering School of Mézières) was a military engineering school in what is now Charleville-Mézières, France.

It was founded in 1748 on proposal of the comte d'Argenson, then Secretary of state for War, and Brigadier Nicolas de Chastillon, commander of the citadel at Charleville-Mézières, with the aim of modernizing the town's fortifications.

It was housed in the palais des Tournelles, the residence for the governor of Mézières.

Philip III of Burgundy built the first palais des Tournelles in 1409, which was rebuilt by Louis Gonzaga, Duke of Nevers in 1566.

Henry III of France lodged at the palais in 1583 and after being largely destroyed by fire in 1697 it was again rebuilt in 1732.
