The death of Cardinal Cisneros Historical milestone · Roa, Ribera del Duero, Burgos Image of Roa, not of the place itself. A historical event that took place in Roa, a town in the Burgos section of the Ribera del Duero, where Cardinal Francisco Jiménez de Cisneros, regent of Castile, died on 8 November 1517. Cisneros was preparing the enthronement of the new king Charles I and sought to meet with him; as the royal retinue moved slowly without fixing a date or place, he set out to meet it and a meeting was finally arranged for 5 November. Gravely ill, he could not complete the journey and died in Roa three days later. The town was then a walled stronghold, fortified by order of Queen Violant of Aragon from 1295. 1517 Photo: Raúl Hernández González from Aranda de Duero, Spain (CC BY 2.0) What to see and do in Roa
