Miraflores Charterhouse () is an Isabelline style charterhouse, or Carthusian monastery of the Order of the Carthusians, built on a hill (known as Miraflores) about three kilometres from the center of the Spanish city of Burgos, autonomous community of Castile and León. Its origin dates back to 1442, when King John II of Castile donated a hunting lodge outside Burgos, which had been erected by his father Henry III of Castile "the Mourner" in 1401, to the Order of the Carthusians for its conversion into a monastery, thus fulfilling his father's wishes, as stated in his will. A fire in 1452 caused the destruction of the pavilion, and construction of a new building began in 1454. It is this building, which was placed under the patronage of Saint Mary of the Annunciation, which exists today. The construction was commissioned to Juan de Colonia, and was continued after his death by his son, Simón de Colonia, who completed the structure in 1484 at the behest of Queen Isabella I of Castile, surviving daughter of king John II of Castile and queen Isabella of Portugal, whose impressive buried are housed in the monastery. It is a late-Gothic jewel, and its highlights include the church, whose Isabelline style western facade is decorated with the coats-of-arms of its founders. The monastery consists of a single nave with stellar vault and side chapels, and is topped by a polygonal apse. Situation and access The Charterhouse is 3 km east of the city center of Burgos, in the parque de Fuentes Blancas, close to the Arlanzón River. The monument is easily accessible from the city of Burgos, and can be reached along an easy footpath in a natural setting. It is possible to go by bus or taxi from the city, and it has free parking for private vehicles and buses. Visits are free and open to the public. Origins First in 1401 was erected the Palace-alcázar of Miraflores, built by King Henry III of Castile "the Mourner". Later, the Miraflores Charterhouse was founded in 1442 after the donation to Order of the Carthusians by King John II of Castile inside the Palace-alcázar of Miraflores. That original monastery, originally placed under the patronage of Saint Francis of Assisi, suffered a fire in 1452 causing a new approach to the building according to the current design, which was commissioned architect Juan de Colonia, who worked at that
