The Early Neolithic settlement is situated in the Gradets locality near the village of Mayor Uzunovo, Vidin municipality. The archeological excavations were carried out in the autumn of 2013. All trenches yielded artefacts dated back to the Early Neolithic.
Structure 1 is damaged by the agricultural cultivation of the soil. The structure is a large conical depression 2.1 m wide filled with dark brown to gray ashy sediment. Remains of a destroyed fireplace and ashes were discovered in the upper part of the structure. Structure 1 was 80-90 cm dug into the ancient surface.
Structure 2 is an oval-shaped negative form. Six complete ceramic vessels were found in situ on the bottom of the structure. The recorded stratigraphic sequence is the following: a layer of plough soil, an Early Neolithic layer which is thicker in the areas where structures have been discovered and sandy sediment of yellowish color.
The pottery yielded by the three trenches is grey to black in colour and has organic temper in it (fine chaff particle most probably from the animal excrements added to the clay). Four technological groups are defined based on the color of the surface. Sherds with painted decoration were not discovered. There are a bone harpoon, bone arrowheads and ceramic labrets among the small finds.
The Early Neolithic Mayor Uzunovo-Gradets site is contemporary to the Protostarchevo I-II culture. It is the first archeological site in the Vidin region marking the territorial connection between the settlements of the Protostarchevo culture in present-day Eastern Serbia and the Ohoden-Valoga site in the Vratsa region in present-day Northwestern Bulgaria.
