In 1951, archeologist Osman Habibulla began excavation in the settlement, clarifying the stratigraphy and cultural strata of the area.

As excavators had found, the town features a cultural layer with the total depth of 22 m. The earliest 9 m of this belongs to the Neolithic.

At each of these layers a variety of artifacts were found: pottery dishes, cattle-breeding and agricultural implements, adornments, weapons etc.

[1] Soviet scientists decided that Kultepe (Kul'tepe) is the place where the first items made of copper–arsenic alloys, dating back to the 4th millennium BC, were found in the South Caucasus.

The Alikemek–Kul'tepe culture covered the Ararat Plain, Nakhchivan, the Mil’skoj and Mugan Steppes and the region around Lake Urmia in north-western Iran[4][5] Kültepe-2 is located about 1.5 km north of Kultepe 1, or about 10 km north of Nakhchivan on the west bank of the river between the villages of Kültepe and Didivar.

[6] Nakhchivan Tepe is yet another important Chalcolithic settlement in the area that is dated to the first half of the 5th millennium BC.

The settlements in the Lake Urmiah basin traded the obsidian from the deposits of the Zangezur mountain range, and Nakhchivan was the intermediary.
