Large museum of science and technology. Has a particularly good collection of military aircraft, and a large steam locomotive. However, not accessible to the general public usually - you have to have an invitation to the METU campus or TEKNOKENT to pass security.
METU Science and Technology Museum is a museum established within the campus of the Middle East Technical University, Ankara, Turkey. The museum is aimed to present the modern technological tools as well as technological past of Turkey.
