The Superman Building in Providence has been included on the US National Trust for Historic Preservation's annual list of the nation's most endangered historic places.
The 2019 list highlights 11 architectural and cultural sites that the private nonprofit deems at risk because of neglect, development or other threats.
The 91-year-old vacant skyscraper is Rhode Island's tallest building at around 131 metres.
Formally the Industrial Trust Building, it resembles the Daily Planet headquarters in the old TV show.
The National Trust's interim chief preservation officer Katherine Malone-France says few buildings in Providence are as iconic or beloved, but the Superman Building has deferred maintenance needs after six years of vacancy.
The National Trust says the list can mobilise support for preservation. This year's list also includes Nashville's Music Row and the National Mall Tidal Basin in Washington DC.
