Les Invalides & Musée de l'Armée

Topped by its gilded dome, the Hôtel des Invalides was (and in part still is) a hospital. Commissioned by Louis XIV for wounded soldiers, it once housed as many as 6,000 invalids. Designed by Libéral Bruand (the foundations were laid in 1671) and completed by Jules Hardouin-Mansart, it's a magnificent monument to Louis XIV and Napoleon.

Behind lines of cannons and bullet-shaped yews, the main (northern) façade has a relief of Louis XIV (Ludovicus Magnus) and the Sun King's sunburst. Wander through the main courtyard and you'll see grandiose two-storey arcades and a statue of Napoleon glaring down from the end; the dormer windows around the courtyards are sculpted to look like suits of armour.

The complex contains two churches - or, rather, a sort of double church: the Eglise St-Louis was for the soldiers, the Eglise du Dôme for the king. An opening behind the altar connects the two. The long, barrel-vaulted nave of the church of St-Louis is hung with flags captured from enemy troops.

Since 1840 the Baroque Eglise du Dôme has been dedicated to the worship of Napoleon, whose body was brought here from St Helena. On the ground floor, under a dome painted by de la Fosse, Jouvenet and Coypel, are chapels featuring monuments to Vauban, Foch and Joseph Napoleon (Napoleon's older brother and King of Naples, Sicily and Spain). Napoleon II (King of Rome) is buried in the crypt opposite his father the emperor.

Two dramatic black figures holding up the entrance to the crypt, the red porphyry tomb, the ring of giant figures, and the friezes and texts eulogising the emperor's heroic deeds give the measure of the cult of Napoleon, cherished in France for ruling large swaths of Europe and for creating an administrative and educational system that endures to this day.

The Invalides complex also houses the enormous Musée de l'Armée, which is in effect several museums in one. Even if militaria are not your thing, the building is splendid, and there's some fine portraiture, such as Ingres' Emperor Napoleon on his Throne.

The Antique Armour wing is packed full of armour and weapons that look as good as new, many displaying amazing workmanship, from the 16th-century suit made for François I to cabinets full of swords, maces, crossbows and muskets and arquebuses. The Plans-Reliefs section is a collection of gorgeous 18th- and 19th-century scale models of French cities, used for military strategy; also here is a 17th-century model of Mont St-Michel, made by a monk from playing cards.

The World War I rooms bring the conflict into focus with uniforms, paintings, a scale model of a trench and, most sobering of all, white plastercasts of the hideously mutilated faces of two soldiers.

The World War II wing covers the Resistance, the Battle of Britain and the war in the Pacific (there's a replica of Little Boy, the bomb dropped on Hiroshima), alternating artefacts with film footage. Also included in the entry price is the Historial Charles de Gaulle (closed on Monday).
