Aulutrena is an ancient Roman castellum located near Çapalı/Karakuyu in modern Afyonkarahisar province, on the shore of ancient Lake Aulutrene. The settlement, believed to have been used as a temporary camp site from the 2nd century BCE, hosted a stone-built garrison particularly during the Severan Period and was expanded during the Byzantine era. It served as an important military center for the strategic control of the region.

History

The history of Aulutrena is a significant indicator of the military and administrative structures in the interior of Western Anatolia. Traces of the earliest human activity in the region date back to the 2nd century BCE, suggesting that a temporary camp or settlement may have been established during this period. However, Aulutrena's identity became distinct, particularly during the Roman Imperial period, as a castellum, meaning a small fortified military camp. Archaeological and epigraphic evidence points to the existence of a permanent, stone-built garrison during the Severan Period (early 3rd century CE). During this period, the establishment of small military outposts like Aulutrena was a common practice within the Roman Empire's strategies for internal security and road control. The settlement maintained its importance during the Byzantine period and was likely further expanded due to its strategic location. This expansion is consistent with the trend of reorganizing settlements and strengthening defense networks across Anatolia during the early Byzantine period. Aulutrena undertook critical military duties for centuries, such as maintaining order in the region and controlling important trade routes.

Geographic Location

Aulutrena is strategically located near the Çapalı/Karakuyu locality in modern Afyonkarahisar province, on the shore of ancient Lake Aulutrene (modern Lake Çapalı). Its coordinates are 38.075122 latitude and 30.276978 longitude. Its location adjacent to the ancient settlement of Aporidos Come indicates that Aulutrena was not merely a military outpost but also interacted with a civilian settlement. This geographic location offered the potential to control transit routes between the regions of Phrygia and Pisidia. Its proximity to the lake provided easy access to water resources, while the surrounding plains offered suitable terrain for military maneuvers. Due to its position on routes leading to the interior of Anatolia, the region held vital importance for military logistics and security during the Roman and Byzantine periods.

Significance in Antiquity

Aulutrena's significance in antiquity stemmed largely from its military character. As a Roman castellum, it was tasked with ensuring the internal security of the Empire and controlling roads and transit points in the region. Its possession of a stone-built garrison, particularly during the Severan Period, indicates that it housed a permanent military presence and was not merely a temporary observation post. Such military outposts played a critical role in suppressing rebellions, combating banditry, and ensuring the security of trade routes. Its expansion during the Byzantine period suggests that Aulutrena's strategic value increased over time, and it likely assumed a greater role in the defense line of the empire's eastern borders or in protecting important arteries in the interior regions. Aulutrena may also have indirectly contributed to the continuity of economic and social life in the region by providing protection to civilian settlements such as the nearby Aporidos Come. Therefore, Aulutrena was not only a military base but also one of the symbols of regional stability and Roman-Byzantine authority.

Coinage

No coins from this settlement are recorded in the NumisTR database. Given that Aulutrena was a castellum, i.e., a military garrison settlement, the absence of coinage is expected for the Roman and Byzantine periods, as the authority to strike coins typically belonged to major urban centers or imperial mints.

Archaeological Remains

Unfortunately, the archaeological remains at Aulutrena have largely not survived to the present day. The small, stone-built fortification mentioned in ancient records and believed to have been constructed during the Severan Period has suffered severe damage over time. This stone structure, located in the modern town of Eldere, was extensively quarried for stone by the 1980s, and modern buildings were constructed over it. This situation has led to the destruction of a large part of the ancient structure or its burial beneath modern constructions. Today, it is quite difficult to observe Aulutrena's original architectural remains on site. However, surface surveys or future archaeological excavations in the region may provide more information about the settlement's precise boundaries and structural features.

Today

The ancient settlement area of Aulutrena is located within the boundaries of the modern town of Eldere, which is part of Afyonkarahisar province. Due to the extensive destruction of the ancient castellum's original stone structure and its burial beneath modern settlement, visitors have limited opportunities to directly view the ancient remains. However, during visits to the region, it is possible to appreciate the strategic importance of ancient Lake Aulutrene (Lake Çapalı) and its surrounding geography. Access to Eldere is provided by road from the provincial center of Afyonkarahisar. The region holds significant potential for history enthusiasts and archaeological researchers to trace the remnants of a lost Roman military outpost and experience the ancient geography.
