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

Hacı Bayram Veli Cami
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.
Anadolu Medeniyetleri Müzesi
Excellent display ranging from prehistory to the proto-Greek and Roman eras.
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.
Ahi Şerafeddin Camii
Built in 1290 in Seljuk style, and repaired in 1330 under Ahi Şerafeddin hence its other name. Well worth the hike up the hill for its finely-carved interior, notably the ceiling supported by a forest of wooden columns. In 2023, five wooden mosques in Central Anatolia were inscribed on the UNESCO World Heritage List - Aslanhane was one of them.
Molla Büyük Cami
A modest building in spite of the name, this was built around 1500.
Gökyay Vakfı Satranç Müzesi
More chess sets ancient and modern than you'd think possible, including weird versions such as the three-sided game.
