Where does Poirot die?

Hercule Poirot died in the last book of the Poirot series, Curtain: Poirot's Last Case (published in 1975). He was very elderly and suffering from Heart disease and Arthritis (although not to the extent that he wished the other protagonists in that novel to believe). Poirot is discovered to have died from a heart attack towards the end of the novel. He had put his amyl nitrite phials out of his own reach which had accelerated his death.
