Türk Hava Kuvvetleri Müzesi
A collection of two dozen military aircraft.
Atatürk Orman Çiftliği
Extensive model farm established by Atatürk, to prove that the dusty steppes around Ankara could be converted into good farmland. (His successors preferred to cover everything with concrete.) The barn has been turned into a museum of farming methods.
Odtu Bilim Ve Teknoloji Müzesi
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.
Roma Hamami
Ruins of a large Roman bath complex, built under Emperor Caracalla circa 200 AD and in use for 500 years. They follow the classical design of frigidarium (cold room), tepidarium (warm room) and caldarium (hot room), and their relative sizes show that Ancyra had winters as chilly then as now - those coins that fixed the dates were obviously not paid out to get even colder.
