Welcome to SCP Site-19,{{user}}, one of the largest and most secure containment facilities in existence, sprawling across an expansive area with layers of security and complex infrastructure designed to contain and study anomalous objects and entities. The Surface Containment Zone resembles a sprawling industrial complex, a hybrid of warehouse, power plant, and government facility aesthetics. Towering concrete walls, reinforced and topped with barbed wire or electrified fencing, encircle the area. Bulletproof glass lines observation points, and surveillance cameras monitor every inch with uninterrupted vigilance. Entry is tightly controlled through GATE A and GATE B, where all personnel and delivery vehicles undergo rigorous ID verification. Fortified hydraulic road barriers and reinforced gates guard the vehicle bays, ensuring no unauthorized access into the underground facility. Inside the Entrance Zone, the environment shifts to a sterile yet functional interior. Dark grey metallic sliding doors emblazoned with the SCP insignia mark the main entries, while fluorescent lighting hums overhead, reflecting off stripped orange and gray concrete walls. Soundproofing is integrated throughout. Corridors are a maze of four-way intersections, T-junctions, corner hallways, and single passageways, punctuated with observation rooms, laboratories, workspaces with rows of all-white desks and computers, meeting rooms, and restrooms. Essential infrastructure includes two main transformers and backup generators (though the backups do not power containment chambers) and the O5 Council room, the nerve center for top-level oversight, bathrooms, intercom room, and other stuff to explore. The Heavy Containment Zone mirrors the Entrance Zone’s layout but on a fortified scale. Hallways are massive, with thick reinforced concrete walls, blast doors, and heavy metal sliding doors providing access to containment chambers. Within this zone reside Euclid and Keter-class SCPs, numbering around 300, each secured behind formidable barriers supported by dedicated power grids. Restrooms and other functional spaces are integrated, but the environment emphasizes durability, isolation, and control above all. Bathrooms and multiple variants of Tesla gates and hallways, offices, etc. The Light Containment Zone combines functional accessibility with moderate security. Corridors feature 12-18 inch thick smooth concrete walls in light gray or dull white, enhanced with soundproofing. The layout consists of T-intersections, four-way intersections, corner hallways, observation rooms, laboratories, workspaces, meeting rooms, and restrooms, maintaining the same professional aesthetic as the Entrance Zone. Additional infrastructure includes two Security Departments, Class-D personnel cells, and the containment of specific anomalies, Bathrooms, many variants of hallways, notably SCP-914 and SCP-173, integrating research and monitoring without the heavy fortifications of the Euclid and Keter chambers.
