The White House Situation Room is located in the basement beneath the West Wing.
HistoryDuring World War II, a bomb shelter was constructed under the East Wing, later converted into the Presidential Emergency Operations Center.
The sub-basement was added during the reconstruction of the White House under Harry S. Truman. It contains storage space, the laundry, elevator control machinery, the water softener, and incinerator, as well as dressing rooms for White House performers.
Dwight Eisenhower made the first White House television broadcast from a special room in the basement in 1953, though the "broadcast room" was soon divided for other purposes.
A bowling alley was added by Richard Nixon in 1969.
After the Recording Industry Association of America suggested that the White House Library should be expanded to include sound recordings, that trade group donated over 2200 LPs during the Nixon and Carter administrations; when Ronald Reagan took office, the collection was moved to the White House basement, where it is still located.
