White House Near Collapse: An Unprecedented Reconstruction

2024-12-14

In 1948, the White House, worn down by war damage and hasty renovations, faced imminent collapse due to structural decay and inadequate foundations. President Truman and his family were relocated, initiating a three-year comprehensive reconstruction. This project not only repaired the critical structural issues but also modernized the White House, adding basements, expanding utility spaces, and nearly doubling the number of rooms. A secret atomic bomb shelter was also constructed, reflecting the anxieties of the Cold War era. While the renovated White House was modernized, the removal of original interior elements altered its historical character.
