A Fortress of Finance
The US Treasury Building
Declared a National Historic Landmark in 1972, the US Treasury Building is the oldest departmental building in Washington. The building serves as the headquarters of the Treasury Department. Treasury's responsibilities encompass revenue collection, money production, accounting, and economic policy formulation. Treasury's architectural significance and the department's role in America's economic history rank the building among Washington's most important landmarks.
Like the White House, Treasury has been on its original site since 1800. From 1836 to 1869, the present building was constructed by notable American architects. Following the assassination of President Abraham Lincoln in 1865, the building served as the temporary presidential office of Andrew Johnson while First Lady Mary Todd Lincoln remained in the White House.
