Many feet below the surface staring at the blast lock doors inside a Titan I Intercontinental Ballistic Missile site in California.

100 feet below the surface, inside a pitch dark Titan I ICBM Missile Silo, looking through a blast lock door.
These doors protected the complex from an explosion inside the silo or an attack on the silo. Each of the silos was separated from the complex by 2 blast lock doors. You can see the second set in the background of this image.

Blast doors for Launch Silo No.3 - Beale 851-C Titan I Missile Base
To me, these types of images are really fun to create. This space was pitch dark, so to get this shot, I set up an LED panel at the camera, shining towards the blast doors to get a composition. Once the framing was set, I took a LED panel and placed it beneath the walkway on the right. I also placed a panel behind the ajar door. Lastly, during the exposure, I light painted the circular section of the tunnel, near the camera, with a flashlight.
