Aproi is a strategic settlement located within the borders of modern Turkey, in the ancient Propontis (Marmara) region. Known by different names throughout history, this city gained the status of a Roman colony (Colonia Claudia Aprensis) during the Roman Empire and maintained its importance as Nova Theodosiopolis during the Byzantine period. It was situated at a key point for controlling trade routes between the Mediterranean and the Black Sea.

History

While definitive information about Aproi's initial settlement is limited, it is known that the region hosted Thracian tribes from the 2nd millennium BCE onwards. The name "Aproi" is believed to be of Thracian origin. During the Hellenistic Period, like other cities in the region, it came under Greek cultural influence, but there is no clear evidence that it attained the status of a major city-state. With the Roman Empire's dominance over the region, Aproi was established as a Roman colony under the name "Colonia Claudia Aprensis" in the 1st century CE during the reign of Emperor Claudius. This status indicates that the city enjoyed significant privileges in terms of Roman law and administrative structure. Its designation as a Roman colony played a critical role in the settlement of retired legionaries and the integration of the region into Roman culture. During Late Antiquity and the Early Byzantine period, the city was refounded or extensively repaired by Emperor Theodosius I or II and took the name "Nova Theodosiopolis" (New City of Theodosius). This name change signifies that the city's strategic and administrative importance was reinforced during that period, and it received special attention from the empire.

Geographic Location

Aproi is located in the ancient Propontis region, in the interior of modern Marmara Ereğlisi, near the Muratlı district of Tekirdağ province. Its coordinates are 40.926941 latitude and 27.107356 longitude. This location provided the city with a strategic advantage on both sea and land trade routes. Propontis is a region that controls the vital sea passage between the Mediterranean and the Black Sea and forms the land bridge between Europe and Asia. Aproi stood out in this critical geography due to its proximity to important cities such as Byzantion (Istanbul), Perinthos (Heraclea), and Selymbria. The city's inland location protected it from direct naval attacks while also facilitating its access to the fertile lands of Thrace. This strategic position enhanced the city's importance both militarily and commercially.

Significance in Antiquity

Aproi's significance in antiquity is closely linked to its geographic location and the administrative statuses it acquired. As a Roman colony, it served as an important center for the Roman Empire's presence in Thrace and the spread of Roman culture. Its colonial status helped strengthen Roman law and administration in the region through the Roman citizens who settled there. Economically, it may have facilitated the processing and trade of products (especially grain) from the fertile agricultural lands of the Propontis region. Furthermore, its location at the crossroads of land routes in the region allowed it to become a hub for the shipment of goods from inland areas by sea, or vice versa. Its renaming as Nova Theodosiopolis during the Byzantine period indicates that the city functioned as a military or administrative outpost for the empire and retained its strategic value. During this period, it may also have served as a defensive point, particularly against threats from the Balkans.

Coinage

No coins from this settlement are recorded in the NumisTR database. Despite being a Roman colony during the Roman Empire, it appears that Aproi did not exercise its right to mint coins in its own name, nor have any archaeological or numismatic findings to that effect been discovered. Coin circulation in the region was likely facilitated by issues from larger neighboring cities with minting authority, such as Perinthos (Heraclea), or directly by imperial mints. This situation is a common practice observed in many small to medium-sized Roman colonies.

Archaeological Remains

Detailed information regarding the visible archaeological remains of Aproi/Col. Claudia Aprensis/Nova Theodosiopolis today is limited. Despite the city's long history of settlement, comprehensive and systematic excavations have not been carried out, or structures brought to light may lie beneath modern settlements. However, as a Roman colony and a Byzantine city, the presence of typical ancient structures such as a forum or agora, temples, basilicas, baths, theaters, city walls, and necropolises would be expected in the past. Surface surveys or fortuitous discoveries might indicate traces of such structures. It is probable to encounter finds such as pottery fragments, architectural elements, or tomb remains, especially from the Late Roman and Byzantine periods. While such remains offer clues to the city's former grandeur, large-scale and well-preserved structures are not easily visible today.

Today

Ancient Aproi/Col. Claudia Aprensis/Nova Theodosiopolis is located today within the borders of modern Turkey, near the Muratlı district of Tekirdağ province. The ancient remains of the city are mostly buried underground or lie within modern agricultural lands and settlement areas. Access to the region is provided by road. Although the exact location and remains of the ancient city are generally known by the local populace, there is no organized archaeological park or museum area. No prominent and easily accessible ancient structures are available for visitors.
