Medina Azahara ('the shining city') is the ruins of a vast, fortified Andalus palace-city built by Abd-ar-Rahman III (912–961), the first Umayyad Caliph of Córdoba. Located on the western outskirts of Córdoba, it was the de facto capital of al-Andalus as the heart of the administration and government was within its walls. In 2018, the site was listed as a UNESCO World Heritage site.
Built beginning in 936-940, the city included ceremonial reception halls, mosques, administrative and government offices, gardens, a mint, workshops, barracks, residences and baths. Water was supplied through aqueducts. The main reason for its construction was politico-ideological: the dignity of the Caliph required the establishment of a new city, a symbol of his power, imitating other Eastern Caliphates.
The complex was extended during the reign of Abd ar-Rahman III's son Al-Hakam II (r. 961-976), but after his death soon ceased to be the main residence of the Caliphs. In 1010 it was sacked in a civil war, and thereafter abandoned, with many elements re-used elsewhere. Its ruins were excavated starting from the 1910s. Only about 10 percent of the 112 hectares have been excavated and restored. A new museum on the edge of the site has been built low, with much of the space underground, to minimize disruption to the views of the landscape from the ruins, which are also beginning to be affected by modern housing.
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.
