It is built in the Patagh Pass in the heights known as the Gate of Zagros in Kermanshah Province of Iran.

This structure is located on the way from Kermanshah to Sarpol-e Zahab, on the 15th kilometer from Sarpol-e Zahab; beside an ancient paving which connects the Iranian Plateau to Mesopotamia.

[1][2] Due to changes of the path, now it is located below the road slope.

Parthian and Sassanid eras have been proposed, but most archeologists and historians believe that it has been built during late Sassanid Empire for a variety of reasons.

It is about a five hundred meters walk away from the main road.
