Happy Birthday to the White House

The cornerstone of the White House was laid on October 13, 1792. President John Adams and his wife Abigail moved into the unfinished structure on November 1, 1800, keeping to the scheduled relocation of the capital from Philadelphia. Congress declared the city of Washington in the District of Columbia the permanent capital of the United States on July 16, 1790. …

Constructed of white-grey sandstone that contrasted sharply with the red brick used in nearby buildings, the presidential mansion was called the White House as early as 1809. President Theodore Roosevelt officially adopted the term in 1902.

During the Truman Administration the White House was gutted except for the outside walls and rebuilt. This photo was taken in April 1950.

White House Construction

Gutted to the outside stone walls, deepened with a new two story basement, reinforced with concrete and 660 tons of steel, and fireproofed, the White House was stabilized. The protection of the historic stone walls was so important that workers dismantled a bulldozer and reassembled it inside to avoid cutting a larger doorway out of the walls. Shafts out of windows carried out debris from the inside of the house, and external stairs were built because the inside was completely empty during the renovation.
