The Foundation maintains and operates a large number of facilities worldwide, from small outposts with only a handful of staff to major Sites with thousands of personnel.
- Site-01 is a safe zone that acts as a data backup for all major Foundation facilities worldwide as well as a secure meeting facility for O5 Council members and other high-ranking Foundation personnel. No anomalies of any kind are allowed in proximity of Site-01. The location of Site-01 is strictly classified.
- Site-19, named that way for no particular reason, is located in rural upstate New York. It was originally a hidden weapons research facility run by the US Government. How it came into the hands of the Foundation is unclear, but the first several years of the organization's history were spent outfitting portions of the facility to meet the Foundation's needs (i.e. electricity and water, security measures).
- Site-77 is the Foundation’s newest facility, and it shows. Most of the equipment is new, and it uses the latest and greatest in Foundation tech. Scranton Reality Anchors, Cognitohazardous security protocols, and Mark II amnestics can all be found here. Historically, this Site marks the first time the Foundation could enact large-scale containment procedures and indefinitely expand their containment space. In parallel, Site-77's research capabilities have grown with access to new anomalous materials to study.
There are many other components to Site-77, including a railroad connection to Rome's rail network, sea access, and external defense and habitation structures.
