White House Presidential Emergency Operations Center (PEOC)

The White House contains an underground Presidential Emergency Operations Center (PEOC), a secure bunker and command facility intended for use during national emergencies. The PEOC has been used to shelter the president and staff during crises; for example, senior officials sheltered there following the September 11, 2001 attacks. Public references to hidden White House bunkers and continuity facilities draw on the documented existence and use of the PEOC.
