He died at Viana in Spain in 1507. He was originally buried in a marble tomb beneath the altar of the Church of Santa Maria in the town with an inscription "Here lies in little earth one who was feared by all, who held peace and war in his hand." In 1537, the Bishop of Calahorra ordered the tomb destroyed and the remains transferred to an unconsecrated site outside the church. In 2007, Fernando Sebastian Aguilar, the Archbishop of Pamplona, allowed the remains to be moved back inside the church on the day before the 500th commemoration of Borgia's death.
Jeg leser det som om han fortsatt er i Viana.....?
Og fra en annen wikiartikkel: "Viana is a town and municipality located in the province and autonomous community of Navarre, northern Spain. Cesare Borgia is buried there."
