One portion of the museum depicted Turkey's nine previous coups or attempted coups from 1960 to 2016, coinciding with 531 such incidents across the globe.
It also honored historic figures who stood against colonization such as Mustafa Kemal Atatürk, Abdul Hamid II, Alija Izetbegovic, Mahatma Gandi and Simon Bolivar.
Sezgin Saatçi, who came to the museum with his family, said the museum depicted the coup with much more detail than that heard on TV.
"It really brings memories of that horrible night, the night of treacherous," he said.
Musa Sipsivri, another visitor, said the plotters, would never bring Turkey to its knees, divide its people or pull down its flag.
The 13-year-old Yusuf Taha Asker said the museum was a place everyone should visit and expressed his pride to be a citizen of Turkish Republic.
