of the fort, the walls appeared to be considerably higher than they actually were. Bastions and barracks were possibly covered with tiled roofs. The fort was also protected in the north and south by a defensive ditch. The north section was wide and deep, the south section was wide and deep. The northern ditch could be crossed by means of an earth dam, while the southern one ran completely through, and was probably spanned by a bridge. The berm was about wide. Gates A total of two gate systems were found. These structures—facing north and south—are so-called chamber gates. They had two passages and were located in the central tower bastions on the narrow sides. When the north gate was excavated in 2000, among other things its width could also be determined to be . Like the corner bastions, it protruded about from the wall. The passages were three meters wide. The access from the outside—as with other late antique gates—was probably closed by two wooden door leaves and a portcullis. The tower foundation ran through here and was supposed to accommodate the portcullis after it was lowered. The inner chamber was at the exit to the inner courtyard through a central column (spina) divided with a side length of , this could also be closed by two wooden gate leaves. The inner chamber of the gate measured . The side walls reached a length of . The south gate, however, could no longer be measured in its entirety. The passage was designed a little differently, perhaps due to differing measurements. From here you had direct access to the river bank and the Limes road. In 2003 an angular wall was discovered on the east side of the gate, which presumably had a counterpart on the west side, possibly the remains of an interior portico. Interior The interior layout consisted of casemate-like, multi-story buildings that ran along the Curtain walls, lined up and divided into ten blocks, each with four rooms. Those along the western wall were of different sizes; presumably they served a different purpose. No porticos, which were often observed in comparable forts, could be found in the barracks area. The inner courtyard initially seemed to have been kept free of any development, but in 2002 the remains of a rectangular building, which presumably dates from the 1st century AD, were discovered south of the north gate.
