This Seljuk and Ottoman complex also dates from the 13th century. Battal Gazi was a commander and a hero who joined the campaign against the Byzantines.
The name Eskişehir literally means Old City in Turkish; indeed, the city was founded by the Phrygians in at least 1000 BC, although it has been estimated to be older than 4000 years old. Many Phrygian artifacts and sculptures can still be found in the city’s archeological museum. There is also a museum of meerschaum stone, whose production remains still notable, used to make high quality meerschaum pipes. In the fourth century AD the city moved about ten km northeast, from Karacahisar to Şehirhöyük.
Whenever it was mentioned by ancient geographers, the city was described as one of the most beautiful in Anatolia.
As with many towns in Anatolia, Christianity arrived after Constantine the Great made it the official religion of the Roman Empire. Beginning in the 4th century, records exist of bishops holding office in Eskişehir. The city was known as Dorylaeum in that period. One of these bishops, Eusebius, was heavily involved in shaping the evolving dogma of the church.
