Masouleh is a small mountain village in Caspian Iran. Masouleh architecture is unique. The buildings have been built into the mountain and are interconnected. Courtyards and roofs both serve as pedestrian areas similar to streets. Masouleh does not allow any motor vehicles to enter, due to its unique layout. It is the only village in Iran with such a prohibition. However, the small streets and many stairs simply also wouldn't make it possible for vehicles to enter.
The spectacular architecture of Masouleh is well-known as “The yard of the above building is the roof of the below building”.
Yellow clay coats the exterior of most buildings in Masouleh. This allows for better visibility in the fog.
Buildings are mostly 2 stories (1st floor and below floor) made of adobe, rods and bole. Small living room, big Guest room, winter room, Hall, WC and Balcony are usually found in 1st floor. Cold closet, barn and stable are located at below floor that attaches to the upper floor by several narrow steps inside the building.
There are four main local communities at the village named: “Maza-var” (meaning: beside the Mosque) at the south, “Khana-var” (meaning: beside homes) at the East, “Kasha-sar” (meaning: stretched on top) at the North, and, “Assa-mahala” (meaning: Assad community) at the West. Apparently down-town is the Market (Bazaar) area and also the main mosque of the village, named: “O-ne-ben-ne Ali”.
