After two test excavations conducted in the past at the site of Gradac in Bapska, located about one kilometre south of the village of Bapska, (conducted from 1938 to 1940 by R. R. Schmidt and in 1964 by S. Dimitrijević), in the year 2006, the site was again the subject of excavation. Of the three established archaeological cultures at Gradac (Sopot, Vinča and Baden, while during the recent visit, surface finds from the Bronze Age were also found), after many years of agricultural work, the Baden layer was almost completely destroyed. It is for these reasons that in the summer of 2006 extensive preparations for the rescue excavation of the site began. As part of the preparations, a small part of the plateau on which the settlement is located was surveyed by a georadar (GPR), and the results once again confirmed the data on the exceptional abundance of archaeological artefacts known from previous excavations. Then a series of aerial photographs were taken and the total area of artefact distribution was defined – covering almost 40,000 m2. Several soil samples were taken from several positions on the tell, and several fragments of pottery with traces of paint were analyzed, for which it was determined to be obtained from hematite. Parallel to the mentioned activities and analyses, archaeological excavations began in a small trench located on the northeastern part of the plateau of a prehistoric settlement (B-G 06; cadastral parcel no. 2527, cadastral municipality of Bapska). With the funds available, an area of 60 m2 was opened. On that surface and at a maximum depth of about 20 cm (only in the humus layer), approximately 3000 sherds of very fragmented Sopot pottery and a slightly smaller number of fragments of Vinča pottery were found along with many fragments of stone tools, some animal bones and one find of semi-processed spondylus. Just below the humus, in one part of the trench, a relatively regular cluster of daub appeared. At that point, the excavation was finished and the structure was not more precisely defined. Some of the pottery finds belonging to the Vinča culture show the stylistic, typological and technological features of phase D of Vinča culture established at the site of Vinča. The similarities can be noticed to the extent that the fragments are identical in colour, firing technology, texture, wall thickness and even decoration (e.g. net pattern). Most of the finds of lithics probably originate from the slavonian mountains or Fruška Gora mountain, but a smaller number represents imports of very high-quality material from present-day Hungary, such as the radiolarite of the Szentgál-type (Marcel Burić 2007, Hrvatski arheološki godišnjak 3/2006, 33–34).
