A city high in the Taurus
Sagalassos lies in the western Taurus mountains of southwestern Turkey, in the region ancient writers called Pisidia, near the village of Aglasun in Burdur province. The ruins sit on mountain slopes at a considerable altitude, often given as roughly 1,500 to 1,700 metres, so the climate is cooler and wetter than on the coast. The site is a good counterpoint to the great coastal cities such as Ephesus and Pergamon, since it shows how Greek and Roman urban culture reached the highlands of Anatolia.
Origins and early history
The Pisidians were a people of the mountain interior with their own language and traditions, and Sagalassos was one of their main communities. Evidence shows settlement before the Hellenistic period, but the city’s monumental development came later. Alexander the Great is reported by his biographer Arrian to have attacked and taken Sagalassos on his march through Anatolia in 333 BCE, an episode that made the city known to Greek writers.
Over the following centuries the city absorbed Greek ways. It had a theatre, an agora and public inscriptions in Greek, and its elite adopted Greek names and civic institutions. After Roman rule spread in the region, the city flourished, particularly from the early empire onward. A new provincial structure placed Pisidia under Roman administration, and Sagalassos is described in inscriptions as the leading city of Pisidia, a title that reflects local pride as much as a formal rank.
The Roman city
Most of the visible monuments belong to the first three centuries CE. The best-known are:
- The Antonine Nymphaeum, a monumental fountain on the lower agora, dated to the second century CE. It had a tall, columned facade with niches and statues, and water flowed into basins. Parts have been reconstructed from fallen blocks.
- The Imperial Baths, a large bath complex with heated rooms and decorated halls, built in the second century CE and modified later.
- The Upper Agora and the Hellenistic fountain house, which mark the long history of the civic centre.
- The Heroon, a monument connected to a heroised figure, and the theatre, which is set high on the slope.
- A library building with a mosaic, often called the Neon library after an inscription.
These buildings are part of a pattern across the Roman world, in which water supply and bathing signalled urban prestige. The baths followed the model described in the article on Roman public baths, and the water supply relied on techniques also seen in Roman aqueducts, adapted to a mountain setting where springs lay at higher ground. Reaching a city so high depended on mountain roads of the kind that shaped Roman road travel across Anatolia. Local limestone and marble were used, and the town developed its own pottery, widely known as Sagalassos red slip ware, traded around the region.
How the site was studied
Systematic work at Sagalassos has been carried out since 1990 by a team from the Catholic University of Leuven in Belgium, led for many years by Marc Waelkens, with Turkish partners. The Sagalassos excavation became known for combining traditional archaeology with environmental science. Researchers have analysed pollen from lake sediments, pottery workshops, animal bones and the architecture itself to reconstruct long-term change in the city and its landscape.
A notable feature of the project is anastylosis, the careful reassembling of collapsed monuments from their original pieces. The Antonine Nymphaeum was rebuilt this way, and visitors can see a large part of it standing again. The approach, as at Ephesus, produces a vivid result but involves interpretation.
Earthquakes, disease and abandonment
The city lies in a seismically active zone, and the excavations show repeated damage to buildings. Some collapsed walls and fallen columns are interpreted as the result of earthquakes, and rebuilding followed. A major earthquake in the sixth or seventh century CE is often discussed as a turning point, although the dating of different episodes is debated and not every collapse has a single cause.
Researchers have also suggested that disease and economic change affected the city. The Justinianic plague of the mid-sixth century is sometimes linked to population decline in the Mediterranean, and some studies of the Sagalassos region have proposed a drop in settlement and farming around that time. The evidence is indirect and interpretations differ, particularly on how much plague mattered compared with earthquakes, shifts in trade and local politics. Climate fluctuations may also have played a role.
After the main city declined in late antiquity, a smaller Byzantine settlement continued on the site for some centuries. The occupation grew thin and then ended, and by the later medieval period the city had been abandoned. The stones were reused, and the ruins slowly became the landscape visitors see today.
Why Sagalassos matters
Sagalassos gives a rare view of a provincial highland city in detail, from its Hellenistic roots to its late decline. Because so much has been recorded, it allows comparison with better-known sites. It also shows that the Roman east was not uniform, and that local conditions such as mountain springs, earthquakes and regional trade shaped each city’s story.
