Interment in the crypt of the monument is severely restricted and is allowed only by a parliamentary act for “National Heroes”. Among those buried in its necropolis are Victor , Émile Zola and Alexandre Dumas.
Hugo’s death from pneumonia on 22 May 1885, at the age of 83, generated intense national mourning. Although he had requested a pauper’s funeral he was awarded a state funeral by decree of President Jules Grévy. More than two million people joined his funeral procession in Paris from the Arc de Triomphe to the Pantheon, where he was buried.
Zola died on 29 September 1902 of carbon monoxide poisoning caused by an improperly ventilated chimney. Zola was initially buried in the Cimetière de Montmartre in Paris, but on 4 June 1908, just five years and nine months after his death, his remains were relocated to the Pantheon
At his death in December 1870, Dumas was buried at his birthplace of Villers-Cotterêts in the department of Aisne. In 2002, for the bicentennial of Dumas’s birth, French President Jacques Chirac had a ceremony honoring the author by having his ashes re-interred at the mausoleum of the Pantheon of Paris.
