A military bunker located near Karaj, Iran, in the Alborz Province. The region around Karaj has been historically significant due to its proximity to Tehran and its strategic location in the Alborz mountain range. During the Iran-Iraq War and subsequent decades, Iran developed extensive defensive infrastructure including hardened facilities and underground bunkers to protect military assets and command facilities.
The Alborz mountains have served as a natural defensive barrier and strategic location for military installations throughout modern Iranian history.
