After Pierre L'Enfant was dismissed from the federal city project in early 1792, Jefferson proposed a design competition for the Capitol and the President's House, with a four-month deadline. Thornton's design was officially approved in a letter dated April 5, 1793, from Washington, and Thornton became the Capitol's first architect.

The Cornerstone Ceremony. On September 18, 1793, President Washington laid the Capitol's cornerstone, accompanied by eight other Freemasons dressed in masonic regalia. The cornerstone itself was made by silversmith Caleb Bentley. The event took place at the site of the new Federal City on the Potomac River.
