• Kids still need a ticket: under-18s get in free but must collect one at the tills, so bring ID
• First Friday late opening each month from 6pm to 10pm, entered only from 129 rue de Grenelle on the Esplanade side
• Two entrances, at 129 rue de Grenelle and 2 place Vauban by the Dôme; visitors with reduced mobility should use rue de Grenelle

The Musée de l'Armée fills the Hôtel des Invalides with French military history, from medieval suits of armor and samurai gear to the Napoleonic era and both world wars. Cannons line the main courtyard, and Napoleon's tomb sits under the golden Dôme. The Plans-Reliefs museum shows giant scale models of fortified towns.

Kids who like knights and battles get the most from it; the world war galleries suit older children.
