Golgoli Ancient Settlement and Underground City, Aqueduct
Located about 5 km south of Mustafapaşa village, on the eastern slope of Meryemana Mountain (Kalkolu Tepe) to the west of the Damsa reservoir lake. In the area, there are numerous remains of settlements carved into ignimbrites and fairy chimneys. Additionally, there is a partially closed underground city in this area, commonly known as the Golgoli ancient city among locals. It's possible to see many church structures and other settlement buildings in this area.
The name Golgoli is thought to derive from the Greek word "Gorga," which means rapidly flowing water. Indeed, just northwest of the area where Golgoli city is located, there are two aqueducts. It is believed that water was brought from this area to Mustafapaşa in the past through these aqueducts
