The White House, the architectural symbol of greatness and stability for the American people, has, on occasion, needed a thorough gutting-and we’re not just talking about the administrations that seem to take more pride in their Oval Office curtains than their policies. Between 1949 and 1952 President Harry S. Truman had to find himself a new home to lay his head while the White House, literally falling to pieces at the time, underwent major renovations.

Under Truman’s orders, 66 rooms of the White House were completely razed and re-built after the bathing president almost fell through a dilapidated bathroom floor onto guests gathered in the ballroom below him.

Window openings provide bursts of light into the cavernous interior of the White House, supported only by a web of temporary steel supports. The exterior walls rest on new concrete underpinnings, which allow earth-moving equipment to dig a new basement. The renovations would end up costing taxpayers $54 million in today’s dollars.

The Tunnel connected the West and East Wings and access to the atomic shelter which Truman ordered built after the Russians successfully detonated their first nuclear bomb – deepening the Cold War.
