Metro Line M2, Osmanbey Station, walking for 5 minutes, mainly for the military music performance at 3:00 p.m. every day, to show some of the Ottoman period, during the modern war, the army's many equipment, and even saw some of the equipment, uniforms, scenes and so on of the Turkish army during the period of China's anti-American and aid to North Korea, they were together with the United States to attack Korea, exhibits. Placed in a two-storey building, but the building is very large, the museum was formerly an army school, therefore, there are many exhibits, this place is a military mystery can not be missed; but the military music performance is slightly different from what I imagined before, it was thought that it might be in the outdoor square, soldiers in active military clothes, held military music performance similar to military parade; In fact, there is a small indoor theatre in the pavilion. Dozens of men dressed in military costumes of the Ottoman period, with moustache, some officers and soldiers holding various cold weapons, some carrying various musical instruments, performing military music, playing Ottoman period music, the tune is basically high and magnificent. Because of this culture, this music is not well understood, many tourists even sleep. That's it.
Far away from the Touristy area of Sultanahmet, the military museum is a huge building with tools/armor/ guns dating back to the Hun period (~500B.C.). Located in Sisli area, it gives you a feel of how the rest of Istanbul lives their daily lives. Very well put together museum as all of the rooms are put together based on Tribe, Time Period and Type of military gear. There are a lot of interactive maps to show how tribes moved and changed, as well as the growth of the ottoman empire. Also at 3pm everyday they have a free performance of a traditional Ottoman military marching band. The museum is Open everyday from 10 to 5pm and entrance is up to 10TL
Harbiye district name, the last period of the Ottoman Empire Military Academy Military service buildings of the museum is located was used as the Great Leader Mustafa Kemal Ataturk, the founder of our republic has graduated from this school. Janissary Band of the world's oldest military, domestic and abroad contribute to the promotion of our country with his concerts. The museum is open every day between the hours of 15:00 to 16:00 in case of two sessions of "Janissary Band" concerts can be monitored.
The Harbiye (military) museum is one of the least visited but most interesting museums in Istanbul. When I was teaching English in Turkey one of my students brought me to this museum to see the Mehter concert. In a large auditorium we got to witness a full performance of an Ottoman military band. The Mehter were so famous in their day that they inspired Mozart to write Abduction from the Seraglio.
