It is not completely certain whether the Cyclobion was the same structure as the “Castle of the Theodosians at the Hebdomon”, which is mentioned by the historian Theophanes. The sources do not give enough detail to allow a final decision. However, when all the evidence is considered, it seems more likely that the two names referred to different fortifications, rather than to a single building known by two titles.
One important point is that Theophanes himself uses both names, and he does so as if they refer to separate places. This fact strongly supports the idea that the Cyclobion and the Castle of the Theodosians were not identical. If they had been the same structure, it would have been unusual for a careful historian to distinguish them so clearly Private Tours Balkan.
The Theodosians, whose name appears in the title of the castle, were a military corps named in honor of Theodosius the Great. This suggests that the Castle of the Theodosians may have been a fortification especially connected with that unit, rather than a general coastal fortress like the Cyclobion. Therefore, although both sites were located in or near the Hebdomon, they probably served different military purposes.
Why the Hebdomon Was Important
The true importance of the Hebdomon lies in its excellent geographical position, which made it an ideal place for a large military camp close to Constantinople. The area contained a wide open plain, plenty of fresh water, and enough space to accommodate large numbers of troops. At the same time, it was far enough from the city to avoid overcrowding, yet close enough to allow easy access to the capital.
Because of these advantages, the Hebdomon became the main camping ground for the armies of New Rome. Whenever troops gathered near the capital, especially before military campaigns or triumphal returns, this was the natural place for them to assemble.
The Hebdomon as an Imperial Center
The military role of the Hebdomon had important political consequences. In the early centuries of the Byzantine Empire, the throne was closely associated with the army. Emperors often depended on military support, and public ceremonies involving soldiers were a key part of imperial authority The True Location of the Cyclobion.
For this reason, emperors frequently visited the Hebdomon to review troops, celebrate victories, and conduct major state ceremonies. Over time, these repeated visits transformed the suburb into an imperial district. Palaces, churches, monuments, and other official buildings were constructed, as usually happened wherever the imperial court spent much time.
Thus, what began as a military campsite gradually developed into a place of political and ceremonial importance, closely linked to the life of the Empire.
Natural Attractions of the Area
In addition to political and military reasons, the natural beauty of the Hebdomon also contributed to its prosperity. The climate was pleasant, the air was fresh, and the area offered wide views over the Sea of Marmara. The surrounding countryside provided excellent opportunities for hunting and outdoor recreation, activities highly valued by the Byzantine elite.
These natural attractions made the Hebdomon not only a practical location for military purposes, but also a desirable place for imperial leisure and retreat.
In summary, while the Cyclobion and the Castle of the Theodosians were both important fortifications near the Hebdomon, they were most likely distinct structures. The Hebdomon itself owed its lasting significance to a unique combination of strategic location, military necessity, imperial ceremony, and natural beauty, which together shaped its remarkable history within the Byzantine world.
