Materials in the museum describe how a coup against the people's will risks causing economic crisis, political disability, social depression and foreign dependency in a country.
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.
