Four 22.2 meters thick civilized layers have been found in the time of excavations in the settlement in 1951-1964 under the leadership of O.H.Habibullayev. The second layer of the settlement related to Kur – Araz culture layers on 3.4-4.5 meters over the monument and in 12,4-1 3 meters depth. This 8.5-9 ms. thick layer is rich with material and culture remainders.

These are characterized with farm-living complexes similar to each. The dwelling houses registered in the lower layers have round planes; the top layer houses have mainly quadrangus plane. Some round houses have right-angled extension. River stones, air-brick and clay mud were used as materials of the construction. The first stage of Kur-Araz culture’s dwelling houses have round plane in I Kultepe. The walls of the houses were built with air-brick and faced with clay from the both sides. The building N 34 of the first construction lay was built using 40 x 20 x 10 sm. sized bricks. The floor has been plastered with clay. Pieces of hemisphere shaped clay plate with handles, stone tools and a fireplace have been found. On the same construction layer a house N33 was built using 50 x 24 x10 sm sized air-bricks. The building’s remaining wall’s height is 35-40 cm, the thickness is 32 sm. The diameter is 8.35 meters.
