A military bunker located near Karaj, Iran, in the Alborz region. The site is situated in a mountainous area approximately 50 kilometers northwest of Tehran, a region with a long history of military installations and strategic facilities. While specific details about this particular bunker remain unconfirmed, the area is known for its network of underground facilities and hardened structures, many of which were constructed during the Cold War era and later periods of regional tension.
The rugged terrain and proximity to the capital have made this region a focal point for Iran's military infrastructure development.
