First of all, this is not a museum, but an attraction to raise pride in your country. Of what is really valuable, these are several Ottoman charters and relics displayed on the upper floor at the entrance. Next, you go to the panorama hall under the dome, where you are shown a cartoon about Sultan Mehmet the Conqueror and how he captured "Istanbul" (actually Constantinople). It is impossible to understand something from this cartoon, and it is not necessary, the main thing is that Mehmet is cool and bent everyone down. And this is for 500 lire. The panorama itself is made lazily, the people are not sculpted, but painted on the wall, so you won't be able to check out the costumes.
I gave 3 points out of 5, because at the exit in the bookstore I found beautiful catalogs of mosaics from the monastery of Chora and St. Sophia, 300 lire each😊
A couple of floors with information about how Constantinople was captured, and a spectacular panorama where a light show is shown every 20 minutes. The location of the museum is next to the very wall that is being "stormed" in the museum. I can advise all history lovers
The analogue of the Borodino panorama is only for Turks. It is highly recommended for understanding the Turkish and, in particular, the Istanbul worldview. Especially if you then plan a trip along the coast with a tour of the Greek history of Asia Minor.
