I love military museums, visiting key ones when I have the chance, and this ranks highly among them. This is just the army museum, since the city has separate air force and navy museums. It is housed what is left of an old Ottoman army and cadet facility, the name of the whole part of the city, Harbiye, taken from its past days as a military centre. Part of the museum is obviously old, part new. It has extensive artifacts from the early Ottoman period up through the 20th century, with uniforms, weapons, flags, tents, artillery, etc. There is sadly little actual old authentic janissary equipment, likely due in part to its long decline after the late 17th century and the unfortunate feeling in the early 19th century that they needed to annihilate that once formidable corps, which took place in the so-called "Auspicious Event" or Vaka-i Hayriye. There is also a Byzantine banner and part of the chain the Byzantines used to block the Golden Horn.
