Ancient walls are advanced devices capable of concealing areas of a structure from sight and sensors. The wall itself can be made non-solid or, in later versions, even disappear when instructed.

A similar wall hides the enterance to a hidden Wraith laboratory used for prohibited genetic research. It is unclear if this uses the same technology, or was invented independently.

Known WallsEdit

Two walls have been seen so far, these are:

Janu's WallEdit

Janus used a wall to hide his secret lab whilst conducting research on various technologies banned by the Ancient Council. The wall was located in Atlantis and was triggered by a series of sounds produced by tapping the 3 lights on the wall near it. It became non-solid allowing Janus to access his research without fear of being discovered. (SGA: "First Contact")

Morgan Le Fay's WallsEdit

Morgan used a wall that was impervious to sensors aside from a minute energy signature that is barely detectable even to those looking for it. It was used to protect a tunnel in a cave. The wall was shaped as a rock face that vanished completely when the hidden button near it was pushed. (SG1: "Morpheus")
