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.

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.
Opera Sahnesi
This opened in 1948 and looks it, the grandeur is kinda faded. It hosts theatre as well as opera and ballet.
