Masouleh (Persian: ماسوله, Māsūleh; also known as Masuleh) is a village in the Gilan Province of Iran. Historical names for the village include Māsalar and Khortāb. It was founded in the 10th century AD, and its current population is estimated to be around 800 people.
Masouleh is approximately 60 km southwest of Rasht and 32 km west of Fuman. The village is 1050 meters above sea level in the Alborz (or Elburz) mountain range, near the southern coast of the Caspian Sea. The village itself has a difference in elevation of 100 meters.
The first village of Masouleh is approximately established around 1006 AD, 6 km Northwest of the current village, and it is called Old-Masouleh (Kohneh Masouleh in Persian). People moved from Old-Masouleh to the current village because of Pestilence and neighbor attacks. Some of old families do have a written Ancestral tree as old as one hundred years.
Masouheh-Rood-Khan is the river passing through the village with a water fall 200m away from the village. Many other springs are found around Masouleh.
Masouleh is also surrounded by forest from valley to mount.
Fog is the predominate weather feature of Masouleh. Although it has been written that the community was established around 10 AD, the province of Gilan has a long history.
