Situated within the campus of the MİT, it is dedicated to the history of espionage featuring a collection of spying equipment.

The internal museum opened its door for the first time to the public in history in October 2013 upon request by a major Turkish daily.

[1] The instruments on display in glass cases, categorized as "technical documentation", consist of equipment for espionage techniques in voice (eavesdropping, call recording) and image processing (photograph, video frame) as well as monitoring (audio surveillance, wiretapping).

The c.150 exhibited items include a voice-recording watch, a bug-hiding shoe wedge, a radio transmitter disguised as a personal weighing scale, holed iron bolts, soap and stone piece for hiding encrypted documents or codebook (block cipher) as well as various pieces of spying equipment in the form of utensils like pens, plug fuses, etc.

Also bugs, detected in buildings of Turkish diplomatic missions abroad in the Cold War era between 1967 and 1989, are on display.
