At first masonry was used in front sides and laterals, then in back sides of grotto in next development period of buildings of cave type. Replacing of flat walls by masonry and improvement of people's construction skill leaded gradually to appearance of overground buildings.

The buildings based on artificial caves passed a long way of historical development and became known under the name of Garadan in the history of architecture. Garadans that were built in Azerbaijan were gradually adapted to the local climatic condition and acquired various architectural-planning qualities. Domestic animals were usually kept in such residents as well. According to the historical sources, garadans were used in Azerbaijan until the beginning of the 20th century.

Megalith architectural monuments-cromlechs, menhirs (herdsman's stone), dolmens and Cyclopes buildings were widespread along with the oldest places of residence found in Gobustan (caves, different primitive shelters and etc.).

These monuments made of high stones are called "galadja" or "horukdash" by people. Defense buildings as Chalkhangala near Nakhichevan (Bronze epoch) and Oglangala on the bank of the Arpachay river (II-I thousand years B.C) belonged to Cyclopes buildings. Rocky buildings (Bastam, Danali, Galaoglu and etc.) were found near the Araz river in Southern Azerbaijan.

New towns, defense buildings, grand towers were constructed in connection with birth of Manna state in the territory of Azerbaijan in IX-VII centuries B.C, then Atrapatena state in the south. Research of toms on cliffs of the Urmiya lakeside and monument complex in Hasanli region show that flat of porch type had been built since VII century. The fire altar (where holly fire kept) only religious monument of that time remained till nowadays. Architectural types, appeared in that period, influenced on consequent architectural development of Azerbaijan, as well as architecture of Iran and other Near East states in the Ahamanies period. Fire temples, appeared in connection with fire-worship spreading, are main religious buildings constructed before Islam.

Important steps were taken in town building in the period of Caucasian Albania (IV century B.C -VII century). Strong fortress walls and earthenware water-piping of Gabala town, defense system ("long walls") built Damirgapi (Darband) passage, Chiraggala (VI century), Round Christian temple in Lakit village (V-VI centuries), basilica in Gum village (approximately VI century A.D.), temple complexes in Mingachevir (VII century) show high level of town-building culture. Architectural monuments of Sasanis period particularly attract attention. Gilgilchay wall, prolonged from the Caspian shore to the foot of Babadagh mountain, and Beshbarmagh wall, prolonged from Beshbarmag mountain in present Davachi region to the Caspian shore, create wide idea on development of fortification buildings.

Architectural direction changed in connection with spreading of Islam in Azerbaijan after Arabic occupation (VII century). Construction of buildings of new type as mosques, madrasas (religious school, caravanserais etc. became major line in architecture. Barda, Ardabil, Maragha, Urmiya, Shamaxi, Shamkir, Shabran, Beylagan, Gandja and Nakhichevan were important towns of Azerbaijan in that time. Turning of Shamaxi, Gandja and Nakhichevan into big towns happened in this period.

Christian temples, defense fortification were built in some provinces of Caucasian Albania along with Islamic buildings. Djavanshir tower, built in the territory of present Ismayilli (approximately VII century), and tower complex near Yukhari Askipara village of Gazakh region (V-VIII centuries) particularly attract attention.

Generally, Albanian buildings made in Azerbaijan territories before and after Islam took important role in architectural development. Some of them such as building remains of IV-V centuries in Pashan and Mukhakh villages of Zagatala region, Govurgala (VI century) in Boyuk Galdak village of Shaki region, Albanian monuments (IV-VIII centuries) in Boyuk Amirli village of Gabala region, Albanian church (middle ages) in Oguz town, Albanian church (I century) in Garakand village of Khodjavand region Nagorny Karabakh, Albanian temples in Sos village (IV century), Iatsi village (temple of V,VII and VIII centuries), in Tagaverd village (675), Guneychartar village (1236), Aterk village of Agdara region (V century), Kolatag (614), Gochogot (672, 698), former Dostahir (713), Gasapet (718), Chaldiran villages (XI century), as well as Susanlig (IV-V century), Vang (IX century), Trakhtik (1094), Tsakuri (1131), Mammadadzor (1147), Tug villages (1197) of Upper Nagorny Karabakh, Shushikand (905), Chanagchi (1065 and 1100), Khachmaz (1100), Khantsk (1122), Khndzristan villages (1202) of Asgaran region has been preserved till nowadays.
