Statement of Significance (as of designation - January 12, 1965):
Constructed in four sections over a 31 year period beginning in 1836, this is one of the largest Greek Revival buildings built by the U.S. government in the 19th century. Born of confused architectural parentage, this building nevertheless achieved a unity of design and boldly simple monumentality unsurpassed in American civil architecture. It now houses the National Portrait Gallery and National Museum of American Art.

The landmark was completely renovated in July 2006.

The landmark underwent a $166 million renovation of all system and historic fabric from Jan. 2000 to July1, 2006.
