It's official: Two of the most iconic buildings in the United States-the Empire State Building (1) and the White House (2)- top the list of America's favorite architecture, based on the results of a public poll of the 150 best works of architecture recently conducted and released by Harris Interactive and the American Institute of Architects (AIA). The poll was conducted in conjunction with AIA's commemoration of its 150th anniversary, which occurs in 2007 and is dedicated to "Celebrating the Past, Designing the Future." "This poll of America's favorite architecture confirms that architecture resonates with people," says RK Stewart, 2007 AIA president. "The choice of the Empire State Building shows that when you ask people to select their favorites, they chose buildings and designs that symbolized innovation and the spirit of their community-but also, more importantly-they chose structures that hold a place in their hearts and minds." Rounding out the top five favorite structures were the Washington National Cathedral, the Jefferson Memorial, and the Golden Gate Bridge (3-5 respectively). A complete list of the top 150 structures, based on the results of the poll, as well as information about the architects and designers of those structures can be found at http://www.aia150.org/.
