A modest building in spite of the name, this was built around 1500.

This was built in 1428, restored by Mimar Sinan in the 16th century, and with Kütahya tiles added in the 18th. Hacı Bayram Veli (1352–1430) was a poet and Sufi teacher, and his ornate tomb is a pilgrimage site.

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.

Scrappy remains of the stage and backstage, they haven't restored the seating. Statues from the site are in the Museum of Anatolian Civilisations.

This volcanic outcrop has probably been fortified since the dawn of mankind, but the earliest traces are from the Phrygians of 8th century BC. The castle was reinforced by the Galatians then the Romans. You stroll up through cobbled streets to the double walls and can climb one of the towers, with views of the sprawling city and distant mountains.

Built by the famous architect Sinan in 1566, it's in finely-crafted Ankara stone. The mimber (pulpit) and mihrap (prayer niche) are of white marble.
