Suspected SCP-4000 location circa 1599 CE.

Item #: SCP-4000

Object Class: Euclid Keter

Special Containment Procedures: All information related to SCP-4000 is to be maintained on redundant RAISA Onto/Temporal-Isolated Servers and encoded in the Solid Archive during the next write-accessible interval. Foundation historians are to monitor academic outlets specializing in history and literature for newly uncovered 4000-A narratives, which should be removed from circulation, archived, and replaced with approved forgeries.

Any individuals claiming to have encountered SCP-4000 are to be detained and fully debriefed, with their statements recorded as SCP-4000 narratives. Affected Foundation personnel may be placed on mnestics to improve account accuracy.

Foundation satellite reconnaissance and intelligence networks are to monitor for any locations matching the description of SCP-4000. The O5 Council is to be notified immediately if any locations significantly resembling SCP-4000 are located.

Effective 3/26/1979, no resources are to be allocated to locating SCP-4000.

Description: SCP-4000 is an undiscovered facility located in a variable but always remote location. SCP-4000 is at least 2 km2 in area and roughly follows standard Foundation construction practices circa 2███. A collection of [LEVEL 4/2000 CLEARENCE REQUIRED] are arranged in nested pentagram configurations surrounding the facility, suggesting advanced technology not currently available outside of the Foundation. No physical evidence for SCP-4000 exists at any location. SCP-4000 is only known to the Foundation through 4000-A narratives.

4000-A narratives are a collection of pseudohistorical documents, written histories, and personal testimonies ranging from the classical period to the late 20th century. SCP-4000 instances differ widely in format, style, and language, but display a number of shared attributes.

  • The narrative always includes around a mythical or lost civilization, city, or location.
  • The location contains objects of great value to the author or characters in the narrative.
  • The narratives never describe anyone reaching their destination.

The appearance of SCP-4000 is identical between 4000-A narratives, although the features described and exact wording vary.1 Despite being published in many eras and often relying on metaphor, 4000-A narratives contain sufficient detail concerning Foundation technology and security practices to represent a Class-IV information security breach.

SCP-4000 was first identified in a collection of 4000-A narratives from the archives of the Vatican Holy Office for Secrets and Prophecies (Secretorum Camerus Prophetias) in 1979. The Holy Office viewed SCP-4000 as an infohazard related to Solomon's Temple, and from the 3rd century to the 19th centuries supressed 4000-A narratives by pressuring authors and circulating alternate rumors and documents that lacked references to SCP-4000.

«CHANGE» «After the Foundation assumed containment responsibilities, a search of Foundation archives produced several additional SCP-4000 instances in the form of personal statements and intelligence debriefings. These instances are also attached below.»
