Over the years, presidents have expanded and modified the White House while preserving its historic elegance.

It contains:

  • Lavish public state rooms like the East Room for ceremonies and events.

  • Sweeping lawns and gardens spread across 18 acres of grounds.

The iconic South Portico with its 8 columns opens to the front lawn and serves as a recognizable symbol.

The Capitol: Seat of Legislative Authority

History and Context

The cornerstone for the Capitol was laid in 1793 based on amateur architect William Thornton's neoclassical vision. In 1800 Congress first met in the newly constructed building, which has since undergone expansions including the addition of the cast-iron dome in the 1860s.

Both landmark buildings support this system of checks and balances fundamental to American governance.
