Behind the Roman Catholic Diocese Palace in Alba Iulia an excavation was conducted to carry out rain water drainage pipes. At first three sections were carried out, but later the excavation extended along the palace walls. The archaeological finds in this area can be considered to be rather scarce, as the very narrow excavations did not make it possible to attain adequate depths that would have enabled us to excavate foundations and to attain coherent stratigraphical profiles. Building A The foundation of the east wall is made up of stones and brick fragments laid regularly, with a small quantity of binding matter between them; it is added to the foundation of the building B. The faces of the walls of the two buildings are very similar, but not identical, as at the building A the percentage of bricks is much higher. Building B was built in two phases. The south wall of the building stands on a ruin, very likely the west side of the Roman camp. The Roman wall stands on a foundation made out of small stones, without mortar. The foundation of building B is made out of stones and bricks, and the elevation is built mostly of stone. During the Austrian period the general land systematization was carried out in order to give way to the level differences necessary for the building and functioning of the Vauban fortification and a sewerage system was developed, most of it in operation to this day. The excavated area lies on the berm and in the trench of the Roman camp, reused during the first phases of the mediaeval fortress. The lower border of the trench is supposed to be about -6 m deep, and the upper part of the berm must have corresponded to the bottom of the Roman foundation, at -3.4 m. compact white fabric, covered by many-coloured enamels and decorated by painting.
