Basilica Therma is an important ancient settlement located in the Propontis (Marmara) region of ancient Anatolia, near modern Bursa. As its name suggests, it is believed to have been a prominent center during the Roman and Byzantine periods, known for its thermal springs and the public buildings that developed around them. Its location on general trade routes, coupled with its function as a healing and recreation center, further enhanced its importance.

History

While there is no direct information regarding the exact foundation date of Basilica Therma, the presence of the name "Therma" suggests that the settlement developed around thermal springs and gained importance as a health and recreation center, particularly during the Roman Imperial period. Given the widespread bath culture and thermal facilities during the Roman era, the city may have experienced significant development during this period. The word "Basilica," on the other hand, refers to large, roofed public buildings typically used as courthouses, marketplaces, or meeting places in Roman architecture. This indicates that the city served not only as a thermal center but also had administrative and social functions.

The Propontis region hosted various Anatolian civilizations such as the Hittites, Phrygians, and Lydians from the 2nd millennium BCE onwards, followed by Greek colonization in the 1st millennium BCE. However, the name Basilica Therma evokes a structure more characteristic of the Roman and early Byzantine periods. The region, falling under Roman rule, held a strategic position for the security of the Empire's eastern borders and the control of trade routes. Within this vast imperial structure, Basilica Therma may have existed as an extension or a supporting center for larger nearby cities (e.g., Prusa ad Hypium - Bursa). It is believed that thermal facilities and public buildings maintained their importance during the Byzantine period, and the settlement continued to exist.

Geographic Location

Basilica Therma is situated within the borders of modern Turkey, in the Marmara Region, at coordinates 40.205714 latitude and 29.042755 longitude. It is located in the southern interior of the Sea of Marmara, known as Propontis in antiquity. This location may have rendered the city a transit or stopping point on the road networks between inland Anatolia and the Propontis coast, rather than directly involved in maritime trade. The region is known for its fertile lands and rich natural resources. The presence of thermal springs, in particular, played a decisive role in the city's development. Strategically, it was located in an area capable of agricultural production and potentially near the intersection of important trade routes. Among neighboring cities, Prusa ad Hypium (Bursa), one of the most significant centers of the region in antiquity, can be mentioned. This proximity suggests that Basilica Therma was part of Prusa's economic and social hinterland.

Significance in Antiquity

The significance of Basilica Therma in antiquity largely stemmed from its name-derived "Therma," meaning thermal springs. These springs may have enabled the city to gain renown as a health and healing center. During the Roman and Byzantine periods, thermal baths were an important part of both hygiene and social life. The wealthy and the sick would visit such centers for healing or relaxation. This situation likely made significant contributions to the city's economy, leading to the development of accommodation, food and beverage, and various service sectors.

The presence of the name "Basilica" indicates that the city was not merely a complex of thermal facilities but also a settlement with important public buildings and administrative functions. A basilica was typically a center where legal proceedings took place, trade was conducted, or the public gathered. This suggests that Basilica Therma also functioned as a political and social center on a regional scale. The city was also important as a marketplace for processing and trading products obtained from the surrounding agricultural areas. This multifaceted structure endowed Basilica Therma with a unique significance in the interior regions of Propontis.

Coinage

No coins from this settlement are recorded in the NumisTR database. In antiquity, the authority to mint coins was typically granted to provincial capitals of the Roman Empire, major metropolises, or cities with a certain degree of economic and administrative autonomy. A city's ability to mint its own coins was an indicator of its economic power, political independence, and regional importance. Given that Basilica Therma was a thermal center and perhaps a settlement located within the hinterland of a larger city, it may not have had the need or the authority to mint its own coins. For its commercial activities, it likely used the coinage of neighboring and larger cities (e.g., Prusa ad Hypium) or the general coinage of the Roman Empire. This situation was quite common among ancient cities, and a city not minting coins does not imply its insignificance; rather, it reflects its administrative and economic structure.

Archaeological Remains

Detailed and definitive information regarding the visible archaeological remains of Basilica Therma today is not available. However, based on its name, it can be assumed that large thermal bath complexes, perhaps a basilica structure, and surrounding residential and other public buildings existed here in antiquity. Intensive settlement and agricultural activities in the region may have led to the destruction of ancient structures over time or their burial beneath modern constructions. Future systematic archaeological excavations and surface surveys may reveal clearer information about the city's full settlement plan and structural characteristics. Particularly in areas where thermal springs are located, there is a high probability of encountering traces of ancient bath remains or water supply systems.

Today

The ancient settlement area of Basilica Therma is located within the borders of modern Turkey, in the Marmara Region, near the province of Bursa. Its coordinates (40.205714, 29.042755) indicate a point close to a modern settlement. The region is easily accessible thanks to modern highways and transportation networks. Since Bursa, in particular, remains an important center for thermal tourism today, it can be said that the ancient thermal heritage continues in modern life. The remains of the ancient city are likely hidden beneath modern settlements or agricultural lands and await full discovery.
