Following his victory at the Battle of Austerlitz in 1805, Napoleon decided to build a monument to the glory of his Grande Armée. The Arc de Triomphe was erected up to the level of the vaults by Jean-François-Thérèse Chalgrin, but construction slowed when he died in 1811. Lequeu’s subsequent proposal sought a solution for the design during the intermediary period before the project resumed in 1823. He transformed the two piers into separate military towers, one on the left for soldiers of the newly restored Louis XVIII’s army and the other for the commanding generals and officers, with a monumental statue of the king situated in between.
