The Charterhouse of Jerez de la Frontera architecture is of a Late Gothic style, corresponding to the start of construction in the 15th century, with Baroque aspects dating from the 17th century. The building, completed in the 17th century, has been designated by the Spanish government as an Historic-Artistic Monument.
The impulse behind the monastery dates back to Alvaro Obertos de Valeto, a knight of Genovese descent, appointed during the Reconquista by Alfonso X of Castile to defend the city shortly Alfonso had conquered it from Muslim rule in 1264. Lacking descendants, he left his fortune to establish a Carthusian monastery in the city. It was not until 1475 that this location near the Guadalete River was chosen, of special significance because in 1368 it has been the site of a victorious battle against invaders; the victory was attributed to intercession by the Virgin Mary, to whom a hermitage had been dedicated on the site, under the name Nuestra Señora de la Defensión ('Our Lady of the Defense'), which was adopted also for the monastery.
The Renaissance entryway, designed by Andrés de Ribera, is of particular interest, as are the Chapel of Santa María, and the small Gothic cloister designed by Juan Martínez Montañés. The choir stalls are by Juan de Oviedo de la Bandera (1565–1625); they were originally made for the Convento-Iglesia de la Merced in Sanlúcar de Barrameda and were transferred to the monastery in 1960. The paintings by Juan de la Roelas currently at the monastery also come from that church. Conversely, the Museo de Cádiz preserves numerous paintings by Francisco Zurbarán that were originally from the monastery.
Nowadays, the Sisters of Bethlehem, of the Assumption of the Virgin, and of Saint Bruno continue the long Roman Catholic monastic and spiritual tradition that had been carried on more than five centuries by the Carthusian fathers.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
