was that Wright, she, and her daughter by her first marriage all be cremated and interred together in a memorial garden being built at Taliesin West. Although Olgivanna had taken no legal steps to move Wright's remains and against the wishes of other family members, as well as the Wisconsin legislature, in 1985, Wright's remains were removed from his grave by members of the Taliesin Fellowship, cremated, and sent to Scottsdale, where they were later interred in the memorial garden. The original grave site in Wisconsin, now empty, is still marked with Wright's name. Legacy During his lifetime, Wright continually altered and added to the complex of buildings, all of which were constructed by students. Many of Wright's most famous buildings were designed in the drafting room at Taliesin West, including the Guggenheim Museum in New York City and Grady Gammage Auditorium at Arizona State University in Tempe. Taliesin West continues as the headquarters of The Frank Lloyd Wright Foundation and its several programs. The structure was added to the National Register of Historic Places on February 12, 1974, and was designated as a National Historic Landmark on May 20, 1982. In 2008, the U.S. National Park Service submitted Taliesin West along with nine other Frank Lloyd Wright properties to a tentative list for World Heritage Status. The 10 sites have been submitted as one single site. The January 22, 2008, press release from the National Park Service website announcing the nominations states that, "The preparation of a Tentative List is a necessary first step in the process of nominating a site to the World Heritage List." After revised proposals, Taliesin West and seven other properties were inscribed on the World Heritage List under the title "The 20th-Century Architecture of Frank Lloyd Wright" in July 2019.
