Working with Rachel Lambert Mellon, Kennedy also oversaw the redesign and replanting of the Rose Garden and the East Garden, which was renamed the Jacqueline Kennedy Garden after her husband's assassination. In addition, Kennedy helped to stop the destruction of historic homes in Lafayette Square in Washington, D.C., because she felt these buildings were an important part of the nation's capital and played an essential role in its history. She helped to stop the destruction of historic buildings along the square, including the Renwick Building, now part of the Smithsonian Institution and her support of historic preservation also reached beyond the United States as she brought international attention to the thirteenth-century B.C. temples of Abu Simbel that were in danger of being flooded by Egypt's Aswan Dam.
