On the Danube river bank by the Ridanj stream shore (Livadica stream) 6km downstream towards the east and away from Golubac town, there are the remains of a smaller Roman fort. It represented a part of fortified military border – limes which were stretching along the Danube. In the time of PP Đerdap construction the locality was partially explored. On that occasion the foundation remains were discovered and were of irregular square base. Its north rampart was completely destroyed by the Danube river flow, while the south rampart was 29m long, the east one was 17m long, and the west one was 25m long. It was in use in II and III century, an evidence of what is pottery and other movable excavations discovered during the research.
