The archaeological excavations of 2007 carried out at the ancient city of Hadrianopolis were located in the urban area to the north of the theatre. The excavations covered a surface area of 1200 m2, and the archaeological strata were founded approximately 2, 5 m below the modern layers, after having removed all the upper sterile soils. The excavation continued in the monumental buildings identified during the previous seasons, where the principal phases of occupation of the urban area were recorded. The earlier occupation layers revealed in the eastern sector (north of the excavation), consist of clay-containing soil strata.
These represent the most unstable traces of occupation of the urban area, only stratigraphically identified, apart from the presence of a floor layer built in rammed earth and brick fragments. The materials revealed in the earlier layer date to the late 1st Century AD. The discovery of a channel associated with several wall ruins, relate also to this phase. In a later phase, a structure of monumental dimensions was built in the area, of which, due to a series of interventions in the later centuries, is preserved only the wall on the western side. This structure seems to have been paved with well-joined limestone slabs 10 cm thick. The archaeological material related to the abandonment phase of the structure dates between the 2nd and the 3rd Centuries AD.
The excavation data suggest that sometimes by the mid 3rd Century, a monumental structure, perhaps a public thermae, was built over the abandoned building. Of this, two rooms (one of an apsidal form) and an open area paved with limestone slabs were revealed. A reorganization of the inner spaces of the structure appears to have happened by the 4th Century AD, followed by other interventions in the floors and walls of its rooms. Between the 4-6th Centuries AD, another structure seems to have been built above the ruins of the public structures. Also, to this period dates another construction identified at the southern sector of the excavation area. The construction of this building within the free existing spaces, as well as its orientation, suggest for a church. Above the layers of another destruction layer, visible in all the sectors, the excavations revealed traces of a reorganization phase of the area around room 1, which seem to have happened during the 6th Century AD. To the east and west of the area two rectangular structures with apses were built. The last phases of occupation of the habitation area at Hadrianopololis, is associated with the discovery of a number of walls set perpendicularly to each other, which might have been used to encircle small agricultural properties.
