Date and Circumstances of Diana’s Death
Diana died in the early hours of 31 August 1997 following a high-speed collision in the Pont de l’Alma tunnel in Paris. The vehicle carrying her, her companion Dodi Fayed, and driver Henri Paul crashed at approximately 00:23 CET. Emergency response was rapid, but paramedics were unable to save her.
