Archaeologists have uncovered the remains of an ancient Greek fortress in the Aşağıseyit Mound of Denizli’s Çal district, Turkey, revealing new insights into the military and cultural landscape of Hellenistic Anatolia.
The excavation, led by Associate Professor Erim Konakçı from İzmir Democracy University’s Department of Archaeology, uncovered a well-preserved fortification wall dating to around 280 BCE — a period marked by conflict between the Galatians and the Seleucid Empire.
The fortress, built during the early Hellenistic period, is believed to have served as a military observation post protecting nearby farmland and trade routes. Its position overlooking the Büyük Menderes River valley made Aşağıseyit a key strategic site linking western Anatolia to the central plateau.
Researchers say the find offers rare evidence of post-Alexandrian defense systems established across the region after the fragmentation of Alexander the Great’s empire.
Exceptional preservation reveals original military layout
Archaeologists note that the Hellenistic fortification at Aşağıseyit is remarkably intact because later settlements did not build over it. This rare preservation allows them to study the structure in its original form and understand how regional defense networks operated in the 3rd century BCE.

“The Seleucids, after consolidating power following the Battle of the Elephants, established small fortresses and lookout stations to secure their territories,” said Associate Professor Konakçı. “Aşağıseyit appears to have been one such strategic stronghold, protecting the fertile valleys of western Anatolia.”
The fortification’s architectural features — including its stone construction, elevated placement, and strategic view of the surrounding plains — indicate that it functioned not only as a military site but also as an administrative center controlling trade and agricultural production in the region.
Aşağıseyit’s long history of settlement
While the Hellenistic fortress is the most prominent discovery this season, excavations have shown that Aşağıseyit Mound has been inhabited for thousands of years. Located near major trade routes along the Büyük Menderes Valley, the site comprises eight distinct settlement phases spanning from the Late Chalcolithic to the Roman period.

The mound’s stratigraphy offers a rare, unbroken record of cultural development, Konakçı explained. “Each layer at Aşağıseyit tells a story — from Bronze Age households to Hellenistic fortifications — offering a rare opportunity to trace the transformation of Anatolian life over thousands of years.”
Excavations, which began in 2001, have revealed prehistoric farming communities, early examples of urban organization, and now, defensive architecture reflecting the political turbulence of the Hellenistic world.
Bronze Age discoveries offer a glimpse into daily life
Beneath the fortress layers, archaeologists discovered the remains of a burned house dating to around 2500 BCE. The structure’s intact walls preserved pottery, figurines, bronze and bone tools, and storage vessels. Among the findings were carbonized grape seeds — evidence that viticulture in the Çal region, still known for its vineyards today, began 4,500 years ago.
Archaeobotanical and microresidue analyses indicate that early settlers cultivated grains, figs, and grapes, while also engaging in weaving and pottery production. Infant burials found in ceramic vessels reflect early ritual beliefs in life, death, and rebirth.
“The burned house represents not only a tragic event but also a time capsule,” Konakçı said. “Through its destruction layer, we can reconstruct patterns of diet, craft, and belief that shaped the daily lives of these ancient inhabitants.”
Linking Greek fortifications with Anatolian continuity
The discoveries at Aşağıseyit reveal more than isolated historical moments. They trace the evolution of a site that transformed from a prehistoric farming village into a fortified Greek settlement and later a Roman center.
The Hellenistic fortress connects this continuum, showing how Greek military architecture merged with local Anatolian traditions to form a new cultural identity after Alexander’s empire fractured. Future research will include radiocarbon dating, micromorphological analysis, and geoarchaeological mapping to explore how environmental and social factors influenced Aşağıseyit’s long occupation.
Artifacts from the site will be conserved and exhibited at the Denizli Archaeology Museum, offering both researchers and visitors a closer look at western Turkey’s deep past.
As excavations continue, Aşağıseyit Mound stands out as one of Turkey’s most scientifically important archaeological sites — a place where ancient Greek fortresses, Bronze Age homes, and layers of Anatolian history converge to tell a story of resilience, adaptation, and cultural continuity spanning nearly 5,000 years.
