Meybod Chapar Khaneh
Meybod Chapar Khaneh dates back to the Achaemenid Era. This place was where they exchanged letters, just like a post office.
The task of Chapar Khaneh was to maintain and domesticate acute and young horses. These horses' role was to send and exchange letters and important objects fast. Thus, Chapar Khanehs looked like castles for the defense and protection of these valuables.
