Official Designation: Chemical and Physical Containment Site-DE5

Site Identification Code: GHM-DE5

General Information


Usage: Site-DE5 is an underground containment facility specializing in the isolation of chemical and physical anomalous hazardous materials. Also located at this site are working groups tasked with reviewing the history of anomalies in the GDR and the containment of anomalies originating from that time. Among them is Research Team 25, which is tasked with restoring and sifting through the old files of the Stasi Division XXV. In addition, Site-DE5 has been running a side business mining and selling raw spar since 2015 and hosts a delegation from the Czech branch of the Foundation.

Founded: 27. March 1992

Location: Oberwiesenthal, Saxony

Cover: Known to the public as the "Grube Niederschlag" mine. Managed by a Foundation shell company.

Function: Containment of chemical and physical anomalies, anomalous weapons and other war materiel, and research and reappraisal of the activities of the Red Army in Germany, the GDR government, and former GDR-based groups of interest and individuals.

Size: 4000 m2 above ground, 42.000 m2 subterranean down to a depth of 920 m.

Above Ground Structure


The main entrance to Site-DE5 on the night of Christmas Eve 2002.

Main Access: The main access to Site-DE5 is on Oberwiesentahler Straße and is officially owned by a Foundation front-company. Access to the tunnels is usually barred by a metal mesh gate that can be electrified, but can additionally be barred by several bulkheads. Persons wishing to enter the tunnels must first report to the guard post, which is located in a small house next to the driveway leading to the entrance. A further check follows at a checkpoint in the gallery itself. In addition, in the event of a catastrophic containment breach, the main entrance may be buried by explosive devices. This is then explained to the public as the result of faulty mining architecture.

  • Guard Post Staff: Both checkpoints are manned around the clock by three guards, each equipped with an HK SFP9, pepper spray, taser pistols and telescopic baton. In addition, each guard has access to two HK MP5N submachine guns. The second guard post also has access to three HK433-12.5" assault rifles and can lock the main access from the outside and/or inside via bulkhead in case of emergency.
  • Side Accesses: DE5 has several side accesses scattered throughout the elevation into which it was built. These accesses are camouflaged and sealed from the outside and can only be opened from the inside, as they serve as emergency exits. Their tunnels can be detonated if necessary.

Main Site: The main site contains a guardhouse, the main building, storage facilities for mining equipment, and a small test site in a wooded area designed for non-hazardous open-air testing.

Main Building: The main building is made of 50 cm thick reinforced concrete with windows made of 2 cm thick bulletproof glass and has two floors. It houses the mock company's administration and planning facilities.

  • Guardhouse: Like the main building, the guardhouse has reinforced walls and windows. In addition, two inconspicuous embrasures have been built in toward the entrance, which are always manned when one of the guards checks the IDs of new arrivals.
  • Storage Facilities: Since only replaceable resources in the form of mining equipment and consumables are located within these buildings, they are not provided with more security measures than required by federal law.

Operations Yard: The Operations Yard is normally where preparatory work for mining takes place, although logistical undertakings occasionally occur here when an anomaly is to be moved in.

Testing Area: The testing area has 600 m2 of usable area and is surrounded by 4 m high and 1 m thick concrete walls with curved edges. These walls have the appearance of a weathered brick wall on the outside. The site is closed by a steel gate and has a network of individually detonatable explosive devices buried in the ground. In the course of reconstruction works in 2013, an asphalt road was built, which completely encircles the area at the wall.

Subterranean Structure

The main part of Site-DE5 is underground and spread over secondary chambers hewn into the original spiral of the Grube Niederschlag mine, which can be extended almost aribitraily by mining equipment. Because the tunnels have been widened and reinforced as part of this construction, it is possible to drive even very wide vehicles down to the seventh sublevel and back. The road, however, is single-lane and has been supplemented with several niches to allow vehicles to pass each other. To save costs, only the walls, floors and ceilings of newly created chambers and safety areas were covered with concrete and then further finished depending on the purpose. The galleries themselves are left natural to this day and, together with the never-removed trolley tracks on the floor, give the site its characteristic appearance. Lamps are placed in them at regular intervals, and electricity and water connections run through pipes in specially drilled tunnels.

An elevator, whose shaft dates back to the days of the former mine, makes it possible to reach all floors comfortably, even though for safety reasons it is not allowed to transport any anomalies. However, in the event of a containment breach, it can be detonated and the elevator shaft, as well as all the floors, buried or blocked only with bulkheads.

Automatic MK nests equipped with Heckler & Koch's HK GMW have been installed at regular intervals in the galleries and can be activated and controlled either from the administration or by passcode from the entrance checkpoint. Their target acquisition is advanced to the point where they can tell if their targets are allies or intruders, and thus enemies, by the gait of their targets. Up to floor U-5, sanitation facilities can be found on each floor. From floor U-6 onwards, these have not been installed for security reasons.

  • Ground Floor: This is where the entrance hall, underground parking and reception are located. Visitors must surrender all weapons here, abandon their vehicles and submit to a search when entering and leaving the building. This floor also houses the barracks of RTF DE5-𝔎 (5-Karl "Die Kumpel"( i.e. The Miners), which also houses parts of various MTFs.

Gallery to the Administration.

  • Floor U-1 This floor, separated by a long gallery, houses the administration. Here, among other things, the director and the department heads have their offices and their own accommodations. The administration has its own escape tunnel and is specially secured against intrusion. On this floor, separate communication lines run to all other parts of the site, in order to be able to communicate unhindered even during an intrusion from the outside.
  • Floor U-2 This is where the personnel quarters are located, separated into scientific personnel, emergency personnel, miners, and Class D personnel. Also located here are the dining hall, laundry, infirmary, and several recreational facilities such as a gym, movie theater, and bowling alley.
  • Floor U-3 This level houses the archives and offices of the Reappraisal Department. Since many records still exist only in paper form, there are increased security precautions here against fire and water intrusion. In addition, the servers of the site DE5 databases are located here, which also house the file reconstruction program Piecefinder and redundant parts of the security AI KIRA. A special area secured by guards houses the remnants of Division XXV's files.
  • Floor U-4 This basement, sealed off by several reinforced concrete walls, checkpoints and gates, houses the boiler room and power supply. Site DE5 is powered by a classical nuclear reactor, but also draws power from the Chemnitz-Nord cogeneration plant in case of emergency. Several emergency power generators and accumulators are installed here and also on other levels to maintain air ventilation in the event of a total failure, without which the employees at the site would suffocate. Classical mining is also carried out on this level to extract raw spar.
  • Floor U-5 Several test facilities for various weapons systems are located on this floor, these range from test facilities for small arms to the German Foundation's only underground firing range for smoothbore tank guns. Also located here is a station for the underground maglev train that connects Site-DE5 with Site-DE22, Site-DE13, Site-37CZ and Site-60CZ. The station is subject to special security precautions implemented by round-the-clock security personnel and automatic KBA machine guns that can be extended from the walls. Similar to the tunnels, the station tunnel can be closed off by bulkheads or completely buried and, with its additional armament, serves as a line of defense in the event of an anomaly escaping from lower levels.
  • Floor U-6 This floor houses several chemistry and physics laboratories and numerous testing facilities for Safe and Euclid class anomalies. Also housed here are the containment facilities for Safe anomalies and anomalous objects. The containment cells are divided according to "Normal," "Chemical," "Physical," and "Weapon-Grade" specializations, and are distributed throughout various secondary tunnels accordingly with appropriate safety precautions. Due to the versatile fire hazard, all types of fire extinguishers are kept ready on this level, and in addition, individual sections can be optionally flooded with water or carbon dioxide after being sealed by bulkhead. If neither is able to stop the fire, the sealed-off area is allowed to burn out. To prevent the danger of toxic fumes, three times the amount of ventilation systems have been installed on this level, which are directly connected to the chimney. Furthermore, lead-enhanced rooms for tests on radiating anomalies exist here.
  • Floor U-7 The lowest level of Site-DE5 houses Euclid-class objects and non-hazardous Keter anomalies. Similar security measures and isolation cell subdivisions prevail as on U-5 with the addition that security guards are active here around the clock and are appropriately equipped depending on the specialization of the containment area.
  • Floor U-7A High security wing U-7A is connected to U-7 by a long tunnel equipped with several security bulkheads and explosive devices for burial. Dangerous Keter-class anomalies are stored in this area. Their containment chambers can be flooded, evacuated, filled with various gases or buried as needed.

Additional Information

Site-DE5 was officially established on March 27, 1992. Prior to that, as the Germanophone Foundation's area of responsibility expanded to include the territories of the former GDR, a suitable site had been sought to cover Saxony, eastern Thuringia and southern Brandenburg. Finally, the Grube Niederschlag mine, which had been closed the previous year, was chosen because of its unsuspecting location and the infrastructure already in place inside it. Construction work began ten months later and was completed in 1999. This was followed in 2015 by the planned connection to the Foundation's maglev network.


Construction work for the excavation of floor U-5.

The site was initially intended for the containment of chemical and physical anomalies. However, when the remains of Division XXV's documentation were discovered in 2006, the site was dedicated to dealing with the GDR's past and the Soviet Union's occupation due to spare capacity. When it became apparent in 2008 that this required the containment of a large number of weapons, Site-DE5 was given a secondary specialization in war materiel. At the same time, work began on excavating additional secondary chambers for weapons testing of all kinds on the level of the planned maglev station, which is now used for testing secret Foundation weapons projects in addition to experiments with anomalies. The construction work was completed in 2010.

On 16. ██.████, a complete power failure occurred at Site-DE5 due to an outbreak of SCP-016-DE, necessitating the evacuation of the entire workforce. Power was later restored, and upon re-entry, the first inactive instance of SCP-056-DE was accidentally found.

In 2011, all ongoing excavations came to a sudden halt. In an effort to avoid the publicity caused by trucks frequenting Site-DE5, all debris generated during construction had been shoveled into an anomalous garbage can that had been transferred to Site-DE5 for that purpose. It had been assumed that the garbage can had an infinite amount of storage space, but it proved finite in 2011. As a result, it was decided to resume mining operations in the Grube Niederschlag mine for better camouflage and to hire miners for this purpose. These were then approved to work at Site-DE5 after an extensive investigation process. Since 2015, Site-DE5 has been commercially extracting raw spar, initially in large part by emptying the can but since 2016 completely by conventional mining of the raw material underground.

In 2012, there was an incident when the workforces of Site-DE5, at the same time as those of Site-DE16 and all the outposts assigned to these two, stopped all non-essential work to demonstrate against unfair pay to personnel working in West Germany. This action had been announced two weeks in advance and caused some dispute among the O4 council members, since two of them also worked regularly in East Germany. After tough negotiations over four days, it was finally agreed to increase the salaries and other benefits of those affected by 20% annually until the West level was reached. This process was completed in 2018.

Since 2017, Site-DE5 has been in active exchange with the Czech branch of the Foundation, helping to contain and research some of the anomalies in their area of responsibility. That is why Site-DE5 now also hosts a Czech delegation.
