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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
