The Royal Chapel of the Invalides – the Dome Church – is bordered to the west, towards the Boulevard de la Tour-Maubourg, by a rectangle measuring 125 metres by 100 metres, divided into four compartments. Built under Louis XV, around 1750, the buildings were intended for officers. At the level of the entrance to the Dome Church, along the gardens, are the Cour d’Arles and the Cour de la Paix, whose buildings house part of the Institution Nationale des Invalides. Further north, the Cour de Toulon and the Cour de Mars are used by the museum of the Order of the Liberation and the Chancellery of the Order of the Liberation.
