Ancient chugha hill is located at the entrance of Gatvand city and beside the Karun River. This hill had seven temples.
One temple for the queen and the other ones for servants and other people.
And this hill was built for Ontash Gall's (the king of Elam) wife 4000 years ago. In recent years they do some researches in chugha hill and they have found some earthen bricks and statues or even something else.
Also it is said that a group of French historians have found some bricks which were like inscriptions.
