Loaded with weaponry dating from before the Turkish conquest, this museum also does a good job with uniforms, medals, flags and battle-themed fine art, though the text explanations are a bit dense. Exhibits focus particularly on the 1848–49 War of Independence and the Hungarian Royal Army under the command of Admiral Miklós Horthy (1918–43). Outside in the back courtyard is a mock-up of the electrified fence that once separated Hungary from Austria.

Around the corner, along Anjou Bastion (Anjou bástya), with displays detailing the development of the cannon, lies the stone turban–topped grave of Abdurrahman, the last Turkish governor of Budapest, who was killed here in 1686 at the age of 70 while Buda was being liberated. Generously, the tablet reads, ‘He was a heroic foe. May he rest in peace'.
