Hand carved houses in a Kandovan Stone Village
Kandovan is a village in Sahand Rural District, in the Central District of Osku County, East Azerbaijan Province, Iran, with homes carved inside rocks. This is a place where houses are not built on a mountain, but within a mountain. Another interesting aspect is the fact that the rock acts as an energy efficient material, keeping the house cool during summer and warm during winter.
The cone form of the houses is the result of lahar flow consisting of porous round and angular pumice together with other volcanic particles that were positioned in a grey acidic matrix. After the eruption of Sahand these materials were naturally moved and 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.
