 This separation was reinforced in the 19th century with the erection of the tomb of Napoleon I, the creation of the two separate altars and then with the construction of a glass wall between the two chapels.When the Army Museum at Les Invalides was founded in 1905, the veterans' chapel was placed under its administrative control.It is now the cathedral of the Diocese of the French Armed Forces, officially known as Cathédrale Saint-Louis-des-Invalides.
