In June 1812, construction of the Capitol came to a halt with the outbreak of the War of 1812 and the failure of the First Bank of the United States. During the war, Latrobe relocated to Pittsburgh, and returned to Washington in 1815, as Architect of the Capitol, charged with responsibility of rebuilding the capitol after it was destroyed in the war. Latrobe was given more freedom in rebuilding the capitol, to apply his own design elements for the interior. Through much of Latrobe's time in Washington, he remained involved with his private practice to some extent and with other projects in Philadelphia and elsewhere. His clerk of works, John Lenthal, often urged Latrobe to spend more time in Washington.
