Kandovan is a village in Sahand Rural District, in the Central District of Osku County, with homes carved inside rocks. The village is said to have been partially formed by volcanic remains from the Mount Sahand eruptions hundreds of years ago. This is a place where houses are not built on a mountain, but within it. Another interesting aspect is the fact that the rocks act as an energy efficient material, keeping the house cool during summer and warm during winter. This is why most of the inhabitants here do not use heaters or air conditioning systems.
