In the 22nd century, the monastery was ransacked three times by the Andorians looking for a suspected sensor array. On the last of these occasions, in 2151, the Earth starship Enterprise NX-01 visited P'Jem only to find it taken over by a group of Andorian commandos led by Shran. After some initial misunderstanding and a firefight, the commandos and the Enterprise landing party discovered a highly sophisticated surveillance installation in the catacombs beneath the monastery. Captain Archer gave his science officer's scans of the facility to Shran as evidence of the Vulcans' spying. (ENT: "The Andorian Incident")
Though the Andorians gave the monks and surveillance personnel ample warning before the eventual orbital bombardment, the Vulcan High Command blamed T'Pol, who was by then a subcommander, for allowing Archer to expose the facility and recalled her from Enterprise. They rescinded this decision at the request of Captain Sopek after T'Pol saved his life on Coridan. (ENT: "Shadows of P'Jem")
The repercussions back on Vulcan were longer lasting. The First Minister was dismissed, and the High Command forced the resignation of T'Pol's mother from the Vulcan Science Academy. The evidence of treason they used had been fabricated; even so, T'Pol had no way to restore her mother's position except by marrying into Koss's influential family. (ENT: "Home")
Arev identified Archer as the man who was responsible for the destruction of the monastery on P'Jem after he learned that T'Pol was the daughter of T'Les. Archer assumes this will be held against him, however, Arev remarks that the captain's actions exposed the Vulcan High Council's "hypocrisy." (ENT: "The Forge")
- In the backstory of Star Trek Online, P'Jem was rebuilt by a coalition of Humans, Andorians and Vulcans in 2170, and access is restricted to protect the sanctity of the monastery. One of the early Federation missions, "Diplomatic Orders", partially takes place there, as the player character hunts down an infiltrator from Species 8472 ("Undine") disguised as a Vulcan ambassador.
