Ayasuluk Fortress sits on the hill high above Selçuk. This hilltop site has been settled since the Neolithic period, but the fortress dates from the Byzantine era and the fortifications were extended by the Seljuks. The mighty enclosure wall had 15 rectangular towers.
Within the walls are several remnants of houses and a small Seljuk mosque. The views over town and the surrounding countryside are wonderful from the hilltop, making a trip here well worth the uphill walk. Archaeologists are still excavating the site, so it is sometimes closed to visitors
