P3R-233 is the site of the Quantum Mirror that takes Dr. Daniel Jackson to an alternate reality.
The Stargate is in an interior room below ground. Heavy equipment of indeterminate function fills the room. The equipment is labeled in a language that is not recognized by Dr. Jackson, he can only identify it as "definitely alien."
The facility includes an artifact room filled with items from different cultures, all tagged and labeled.
The planet was destroyed by the Goa'uld and left contaminated by radiation. As a warning an ominous totem is left behind. It is the symbol of Korosh-ni. It is for any Goa'uld or Jaffa who may pass through the Gate. Loosely translated from Goa'uld it means, "Turn back."
In the alternate reality visited by Dr. Jackson, the planet had been visited, but the quantum mirror was not found there. The planet was determined to be the source of a message that warned of the incipient attack by the Goa'uld and gave the coordinates for the source of the Goa'uld attack.

In the alternate reality left by Dr. Samantha Carter and Major Charles Kawalsky, the Quantum Mirror was found on the planet and moved for study to their Stargate command. (3.06 "Point Of View")
