Rashkan Castle was a castle in Tehran Province in northern Iran. It was located near Cheshmeh Ali, Shah-Abdol-Azim shrine and Fath Ali shah inscription (Cheshmeh-Ali). It was built during the Parthian rule of Iran.
The name comes from Arsaces I of Parthia, the first king of the Parthians. Some of the war items found there are now housed in the National Museum of Iran.[1]
