Construction Type:

This structure includes a pool located at a spring called Kani Boulagh, the covered water guidance part and the conveying canal that carried the water from the spring into a reservoir called “Sangar” and then the water was diverted to the Sari Ghorkhan Castle through an earthenware water passage. The castle is approximately 8 km far from the spring. The part on which more research has done is the halfway reservoir of “ Sangar” that its rough dimensions is equal to a football pitch’s and is dug in the rather soft and impenetrable layers of conglomerate and marn.
The parts likely to collapse or slump include a retaining wall of 30 m wide, 60 m long and 130cm thick made of lime stone blocks.
 

Features:

Considering its construction time, the comprehension and perception of the nature’s regulations by its constructors are praiseworthy.
 

Location:

This structure is located in the city of Tekab. The halfway reservoir is located 25 km far from western Tekab and 1 km from northern Nokhod Dareh. One can get there taking Tekab-Goldareh roadway. The distance between the village of Goldareh and Sangar reservoir is 8 km.
 

Purpose:

It’s less likely that the only reason for building this construction was only to provide the castle with water. The inhabitants of Goldareh village would use that too. The village was probably built to protect the construction. This needs more technical research.
 

History:

The building of the dam goes back to Mana period in 2800 years ago.
