Reunited in death fidel castros remains rest at che guevara mausoleum
That's not accurate. Fidel Castro's remains are not buried at the Che Guevara Mausoleum.
After Fidel Castro's death on November 25, 2016, he was cremated and his ashes were taken on a nine-day journey across Cuba, stopping at various cities and landmarks. The ashes were placed in a special urn at the Santa Ifigenia Cemetery in Santiago de Cuba, where many other Cuban revolutionaries are buried.
Che Guevara, on the other hand, was executed in Bolivia in 1967 and his body was buried in an unmarked grave. In 1997, his remains were exhumed and reburied in the Plaza de la Revolución in Havana, Cuba, where a large mausoleum was built to honor his memory. The mausoleum is known as the Mausoleo de Ernesto Che Guevara.
So, while both Fidel Castro and Che Guevara are important figures in Cuban history and revolution, their remains are not buried together at the Che Guevara Mausoleum.
