Kandovan, Osku

Kandovan (, also romanized as Kandovān and Kandavān; also known as Kanvān) is an ancient village in Sahand Rural District in the Central District of Osku County, East Azerbaijan Province, northwestern Iran. It is situated in the foothills of Mount Sahand, near the city of Osku. At the 2006 census, the village population was 601, in 168 families.

The village exemplifies manmade cliff dwellings which are still inhabited. The troglodyte homes, excavated inside volcanic rocks similar to dwellings in the Turkish region of Cappadocia, are locally called Karaan. Karaans were cut into non-welded ignimbrites, also called "ash-flow tuffs," of Mount Sahand. The cone form of the houses is the result of the erosion of ignimbrite layers consisting of porous, round and angular pumice together with other volcanic particles that were positioned in a grey, acidic matrix. During the eruption of Sahand, pyroclastic flows formed the rocks of Kandovan. Around the village the thickness of this formation exceeds 100 m and with time, due to water erosion, the cone-shaped cliffs were formed.
