At that time, the communities dwelling along the Western Black Sea coast and around the Varna Lakes have reached the summit of their development. The variety and perfection of the earthenware and the idol plastics make it possible to discuss real achievements in the fields of art and religious life of the prehistoric man.
Interesting objects discovered in the necropolises by the town of Devnja reveal the notions of the then people about the after life.

  During that age, characteristic for the Varna Lakes are the 'pile dwellings' remnants of which such as pottery, bone, flint and stone tools, small idol figures, etc. are to be found in 2,5 m. to 8 m. under the present water level. Most probably the dwellings were situated along the coast of a deeply cut into the land sea bay and have been submerged by the rising of the sea water level. The living conditions in the 'pile dwellings' were equal to those in the inner part of the region but obviously along the sea coast was concentrated a metallurgical center processing copper and gold. The artifacts from these dwellings do not defer to those from the land dwellings. Remarkable is the clay head representing probably some local deity.
