Les Invalides is a walled complex of five courtyards under a gilded dome, and Napoleon lies in a pit below the church floor so that everyone looks down at him. You come in from the north into a paved courtyard 102 metres long, bronze cannon standing along it under two floors of arcades, the dome closing the far end. Behind the high altar a doorway leads down to a white marble gallery level with the sarcophagus, sunk in a round well six metres below the floor, with twelve stone figures of Victory around it.
The place was built to get wounded soldiers off the streets. Veterans of Louis XIV's wars were begging on the bridges, so a royal edict ordered a home for them: dormitories, workshops and an infirmary with 2,140 beds, holding close to four thousand men at its fullest. That is still what it is. About a hundred disabled veterans live here today, in wards you cannot enter, and the long courtyard you walked in through is where France holds its state funerals. Napoleon arrived a great deal later than the buildings standing round him.
