Varna Chalcolithic necropolis was discovered in 1972. It is located in the western industrial zone of Varna. Until 1991, 294 graves were researched whereas about 30% of the area remains unrevealed. In total there are 3078 finds of the world's earliest processed gold with the weight of 5.763 kg. The necropolis refers to the Late Chalcolithic Culture "Varna" and according to a study in the Oxford Laboratory dates from 4600-4400 BC.
One of the most interesting complexes is Grave № 36, located in the southeastern sector of the necropolis. There is no skeleton found inside it and is therefore considered to be a symbolic tomb - cenotaph. The grave pit has a size of 1.20 x 0.85 m, located north-south. Findings are found in three layers at a depth of 0.68 m to 0.95 m from the surface. They are made of ceramics, kaolinite, bone, Dentalium mussels, flint, marble and copper. There are 857 gold objects with a total weight of 0.789 kg.
