In different parts of Iran like Mahneshan County in Zanjan Province, there is phenomenon named Doodkesh-e Jen which is considered as one of the tourist attractions of the area.
Doodkesh-e Jen is located 20 kilometers from Mahneshan County and 120 kilometers from Zanjan. In geology, this natural phenomenon is called "Hoodoo". In fact, it is a type of mushroom-like stone created as a result of erosion. It looks like a high thin minaret on which there is another stone.
Doodkesh-e Jen and Beheshtan/Mahneshan Castle are the tourist attractions of Zanjan that have been very little up to now. They lie near Behstan Village and Mahneshan County, approximately 110 kilometers from Zanjan.
