Iran 🇮🇷 , Kandovan village

It is located in the Sekhend volcanic massif at the foot of Mount Sahand, between Tabriz and the city of Osku. Tourist attraction. 

The village is known for its dwellings, streets and staircases cut into igneous rock. Many of the houses are located both inside the mountain and protrude beyond it. The oldest buildings date back to the XIV century. The settlement was founded by people who fled from the Mongol invasion. 

Some of these cave dwellings are more than 700 years old, and they are still inhabited. Due to the composition of the breed, the houses maintain a comfortable climate all year round. The village is registered with the National Heritage Society of Iran

The width of the walls in houses varies from 2 to 3 m, and good insulation is the main factor of energy saving. There is a very low temperature difference inside the structures, since in winter the temperature in the room is higher than the air outside, and in summer vice versa.
