While researching the subject, I found out that there is a bowling alley below the White House. The White House Bowling Alley is a one-lane bowling alley in the basement of the White House under the Noth Portico.
Bowling lanes were first built in the ground floor of the West Wing as a birthday gift for President Truman in 1947 (in the location of the present-day Situation Room; Truman didn’t care for bowling himself, but allowed staff to start a league. These were moved to the Old Executive Office Building in 1955 to make way for a mimeograph room.
In 1969, President and Mrs. Nixon, both avid bowlers, had a new one-lane alley built (paid for by friends) in an underground workspace area below the driveway leading to the North Portico.
