LOS ANGELES (AP) -- State and local officials in California have unveiled a plaque designating architect Frank Lloyd Wright's Hollyhock House in Los Angeles as a UNESCO World Heritage Site.

The Los Angeles Times reports Democratic U.S. Rep. Adam B. Schiff and Los Angeles Councilman Mitch O'Farrell delivered remarks at the ceremony. Los Angeles Department of Cultural Affairs officials also attended the unveiling at the house, which was built between 1918 and 1921 and earned the city its first World Heritage designation.
