Century Plaza Hotel, Los Angeles, California
A Los Angeles
landmark since 1966, the Century Plaza Hotel was designed by architect Minoru Yamasaki, who would later design New York's World Trade Center towers.
Though the 19-story hotel recently underwent a U.S.-$36-million facelift, new owners plan to level the Century Plaza and replace it with two environmentally sensitive towers--landing the building a spot on the National Trust for Historic Preservation's 2009 list of the 11 most endangered historic places in the United States.
Speaking at the hotel on April 28, 2009, actress and preservationist Diane Keaton said: "All over Los Angeles, too many of our great modern buildings have already fallen to the wrecking ball.
"We need to lead by example and show the rest of the country that buildings are renewable, and we shouldn't be throwing them away."
