The lycée militaire de Saint-Cyr (or Coldo) is one of six lycées de la Défense [fr] (formerly 'lycées militaires') of the French Ministry of Defence.
Situated at Saint-Cyr-l'École (Yvelines), it occupies a particularly historic building - it succeeds the Maison royale de Saint-Louis, the Prytanée militaire and the École spéciale militaire.
The lycée's motto is "La véritable école du commandement est donc la culture générale [The real school of command is therefore general knowledge]".
