Masouleh is a village in the province of Guilan in Iran.

Masouleh is a village in the province of Guilan in Iran. The historical names of the village are Maassalar and Khortab. The village was founded in the 10th century and its current population is estimated at 900 inhabitants.

Masouleh is about 60 km southwest of Rasht and 25 km west of Fouman. The village is 1,050 meters above sea level in the Elborz range, next to the southern Caspian Sea. The village itself has a difference of more than 100 meters.

Although it has been written that the community was established around 10 AD, the province of Gilan has a long history. The first village of Masuleh was established around 1006 AD, 6 km northwest of the current city, and it is called Old-Masuleh (Kohneh Masuleh in Persian). People moved from Old-Masuleh to the current city because of pestilence and attacks from neighbouring communities.

Fog is the predominant climate of Masouleh.

The architecture of Masouleh is unique. The buildings were built on the mountainside and are interconnected. Courtyards and rooftops serve as pedestrian spaces in the same way as streets, since the roof of a house serves as a courtyard to the house below. Masouleh does not allow access to motorized vehicles because of its unique design. It is the only village in Iran to have such a ban. The narrow streets and the many stairs would not allow anyway vehicles to circulate in the village.

The exterior of the buildings is covered with ocher / yellow clay. This allows a better visibility in the fog.
