SCP-4814 (Center).

Special Containment Procedures: Due to the size and remote location of SCP-4814, full containment is currently neither possible or necessary. All photos of Ganymede are to be altered to remove SCP-4814 if SCP-4814 is present. Astronomers involved in the study of Ganymede are to be monitored by embedded Foundation agents.

Extraterrestrial Site-713 has been constructed on the surface of SCP-4814 to house researchers and task forces. Mobile Task Force Lambda-31 ("Stone Cutters") and Orbital Task Force Gamma-1 ("Multiworld Travelers") have been assigned to exploration and securing SCP-4814.

A series of checkpoints and Forward Operating Bases have been established within the lower tunnels of SCP-4814. All checkpoints are to be controlled and defended by Mobile Task Force Zeta-9 ("Mole Rats").

Description: SCP-4814 is a massive superstructure located in the north pole of Ganymede1. SCP-4814 covers approximately 100 km² on the surface of Ganymede. The surface portion of SCP-4814 consists of several thousand buildings of various function connected by walkways.

Within the largest structure on the surface level is a centralized junction leading to subterranean levels of SCP-4814. The first subterranean level of SCP-4814 begins 20 meters beneath the surface of Ganymede, and extends to an unknown depth. This level is predominantly composed of buildings used in the research and experimentation of various fields of science.

The second level of SCP-4814 compromises a total area of approximately 65 km². All areas and rooms within the second level are entirely dedicated to a industrial park, often towards major heavy industry. Several storerooms within the second room include advanced military and industrial mining equipment produced from still operational factories within SCP-4814.

The third level within SCP-4814 is composed of thousands of decayed concrete tunnels leading to various points throughout Ganymede. Each tunnel measures with a height of 60 meters and a width of 65 meters. The length of each tunnel ranges from a minimum of 500 km to a maximum of 4,500 km. The only accessible entrance to the third level are massive circular concrete shafts beginning in several points of the second level.

SCP-4814-1 refers to humanoid entities composed of igneous rocks. SCP-4814-1 instances vary in height and material, however are most commonly seen standing at 1.8 meters and are composed of Basalt and Peridotite. SCP-4814-1 instances perform maintenance on SCP-4814 throughout most of their existence. SCP-4814-1 instances have largely ignored all Foundation attempts of contact. No SCP-4814-1 instance has been observed in the surface area of SCP-4184.


Addendum 4814.1 Discovery

SCP-4814 was discovered in 1997 by The NASA Space Satellite Galileo after astronomers noticed an unusual topographical pattern within Ganymede's North Pole. After a second fly-by of Ganymede by the Satellite New Horizons, SCP-4814 was confirmed to be an extraterrestrial structure.

Foundation Astronomical Command was alerted by NASA shortly after conformation. Construction of Site-713 began after initial Foundation response units reached the surface of Ganymede.
