Preserve the Ambassador Hotel for sure

The famous Ambassador Hotel in Los Angeles is slated for demolition in the future and the city has given the go-ahead for its demolition.But the Hotel(at least the main building)must be preserved forever.The rest of the site could be used for schooling children.After many years of wrangling between conservationists and the city,the conservationists lost.Still,somehow conservationists must find a way to preserve the hotel.This hotel means much more to Los Angeles than the notoriety it achieved for being the site of Robert Kennedy's assassination in 1968.
I also think the Cook County Hospital in Chicago must be preserved and that The Twin Towers in New York must be rebuilt.
