The dual towers of Kharaqan are two brick towers relating to the Seljuq era located in a 29 meter distance from each other and in a one kilometer distance of Hesar village, one of West Kharaqan rural district environs in the Aowj town of Qazvin.

Execution of the bricking of these towers indicate the high skills of their constructors and has turned this building to one of the most spectacular buildings of the 5th century A.D.
