The Roman City Villa (Villa Urbana) was built in II c. in the area of the Canabae,- the civilian settlement to the legion, developing north of the camp of the XI Claudius Legion. The villa was inhabited by a wealthy Roman family. In the following decades it was expanded and completed, and during  the barbarian invasions it was burned and destroyed at the end of III c. .

In the second half of IV c. an imposing public building was built on its ruins with a large hall with an apse and a bathroom. The plan of this public building followed the architectural and construction principles of the residences of city governors and bishops of the IV-VI centuries. Thus it can be referred to the studied bishop's basilica and be considered as the palace of the Dorostol bishops of the IV-VI centuries.
