This is looking from the end of the center bunker across the east gun pit. The chain link fence was put up when they used this area to film some scenes for the TV show Lost. The dark square is the entry to the upper level of the eastern bunker. Theres a large pit to the left of that that goes down to the lower level where the power room was located. The hallway below the one you see is enclosed and protected with barred windows.
