The secular buildings of the Byzantine era in Egypt have not been sufficiently studied. This is often due to the poor condition in which the ruins of most of these buildings are usually due to the influence of time factors on the one hand, or because of the poor construction methods and the lack of architectural interest on the other hand. While the recent scientific excavation of many of these archaeological sites has helped to gradually identify the original form and appearance of such facilities, the interpretation of the identity and function of these architectural ruins remains a matter of controversy. From this point of view, the interest in this study was the Al-Qasimiyah plateau area, in the site known to the people of the region as “Manama Al-Sitt Badriya" on the right side of Al-Kafoury / Burj Al-Arab Road.. Where the mission of the Supreme Council of Antiquities in 2001 partially revealed the remains of two architectural groups representing the southern Including the ruins of a small church, a baptismal basin was found in one of its rooms, while a cemetery was found in another room. As for the northern group, which he singled out for the study, it represents a well-formed architectural group referred to in a report. The mission is summarized as: "A country house belonging to a private estate." The study aims to clarify the various structures and architectural elements characteristic of this complex through a comprehensive understanding and reinterpretation of their potential functions, which may add new characteristics to the identity of the complex by re-imagining the daily practice and the sequence of activities, which may shed new light on some general manifestations of industrial activities in the world ancient in this period, especially Egypt.
