Located in northeast Iran at the foot of Mount Sahand, the mound-like homes are carved from volcanic rock, meaning that most of the materials needed to construct them were already located on site. Technically, the dwellings aren’t true underground homes since a portion of them sits above ground, but since much of the living space is buried, inhabitants can expect cooler temperatures during the day without having to jack up the air conditioning (and saving a lot of energy).
As you can see, the style of the homes isn’t as primitive as you might think since a lot of additions have been made in the last 700 years. There are modern doors and windows mixed in with more ancient looking carved out rooms and openings. While the area might look like its from prehistoric times, it’s actually a hoppin’ resort locale with hotels, restaurants and a special mineral water famed for its healing properties.
