Whitney Mansion, 1895. Constructed in 1875 for millionaire Frederick W. Stevens and designed by George Harney, the mansion was filled to rafters with antiques and furnishings that Stevens purchased in Europe. After Steven's passing, his widow sold the home to Oliver Payne who gave it to his sister Flora and her husband William C. Whitney. The Whitney's had the home remodeled by Stanford White, but only lived their briefly as Flora died in 1893 and William remarried and moved to a different Fifth Avenue mansion. William's son Harry Payne and his wife Gertrude Vanderbilt lived in the home until 1907 when it was sold and demolished. In the 1920s the Heckscher Building (also called the Crown Building) was erected on the site.

Heckscher Building, ca. 1921. Today known as the Crown Building (so named in 1983 for the crown-like look of the illuminated building at night), the 26-story building was completed in 1921 as the Heckscher Building. Designed by architects Warren & Wetmore, the French Renaissance style building was one of the first office towers designed and erected after the passage of the 1916 zoning laws. it was topped by a 12-foot gold-plated weathervane in the form of a rooster. In November of 1929 the Museum of Modern Art opened in galleries on the 12th floor of the Heckscher Building. The first exhibition was a show featuring the works of Cezanne, Gauguin, Seurat and van Gogh. The museum remained until 1932 and its final show in the space was "Modern Architecture: International Exhibition," curatated by Phillip Johnson. The gold weathervane was removed in 1942 and melted down for the war effort. The building was stealthily purchased by Philippines President Ferdinand Marcos in 1981 and soon after had its facade gilded and illuminated by a lighting designer (hence the name change based on its new look). Following the fall of the Marcos regime, the building was sold in 1991. Its most recent sale in 2015 for $1.8 billion made NYC real estate history, a world record price per square foot, $4,564.
