Franco was buried in a grand mausoleum called the Valley of the Fallen, northwest of Madrid, soon after his death in 1975.
His remains will be relocated to the Mingorrubio state cemetery in El Pardo, 12 miles north of Madrid, where his wife is buried.
Thousands of executions were carried out by his nationalist regime during the Spanish Civil War and in the following years.
After World War II, he was seen by many as the last surviving fascist dictator and was ostracized by the United Nations.
It also recognizes the victims of the civil war and the Francoist state and pledges aid to those victims and their descendants.
