decorated with red and white patterns, floral motifs, inscriptions and bordures. In the vault the denarius and antoninianus coins were found, mostly depicting the 3rd century emperors Gallienus, Claudius Gothicus and Aurelian. Viminacium port According to the Roman document Notitia Dignitatum, part of the Roman Danube fleet was anchored at Viminacium. As the locality is not situated on any modern watercourse, either the Danube was flowing further to the south than it does today, or some large arm was separating from the main flow in this direction, leaving the modern fossil riverbed which yields numerous navy artifacts. In 2019, at the old mouth of the Mlava into the Danube (today Drmno coal surface mine) a large iron anchor was discovered, but was stolen the same night it was dug it up. In February 2020, a hewn boat (monoxyl) was found at the same locality. Just a month later, the discovery of the buried ship in the same former riverbed was announced. It was located west of the previous discovery. The ship was discovered at the depth of . It was partially embedded into the sand, alluvial sediment of the river, and partially into the marshy clay sediment, when the river changed its course and the remaining oxbow lake turned into the swamp. Layers above the ship were also mixed, including loess brought by the wind, and solidified mud from frequent flooding. It was excavated, and partially damaged, by the large excavator, when the planks were spotted in its bucket. The ship is extremely well preserved thanks to the specific conditions and high moisture. It is the flatbed ship, built for the shallow waters. The casing for the mast of the auxiliary sail also survived, so as the rudder, stern and the square rowlock for the stern oar. Preserved part of the ship is long, but it is estimated that the entire ship was long and wide. It was definitely a war ship as it has remains of the rostrum. Two monoxyls were discovered next to it. Exact dating will be conducted applying the C4 carbon fixation technique. The geologist will survey the dug to establish the timeline when the river was flowing through here. Though suggested that the ship may be even prehistoric, everything points to the Roman type of ship (Roman, Byzantine, early medieval). The ship is the only such find in Serbia. It will be fully reconstructed, including
