Valencia Cathedral was consecrated in 1238 by Pere d'Albalat, Archbishop of Tarragona, and was dedicated to Saint Mary by order of James I the Conqueror. It was built over the site of the former Visigothic cathedral, which under the Moors had been turned into a mosque.
Most of Valencia Cathedral was built between the 13th century and the 15th century, and this style was mainly Gothic. However, its construction went on for centuries. As a consequence there is a mixture of artistic styles, ranging from the early Romanesque, Valencian Gothic, Renaissance, Baroque and Neoclassical.
The cathedral contains numerous 15th-century paintings, some by local artists (such as Jacomart), others by artists from Rome engaged by the Valencian Pope Alexander VI who, when still a cardinal, made the request to elevate the Valencian See to the rank of metropolitan see, a category granted by Pope Innocent VIII in 1492.
A purported Holy Chalice, believed by many to be the true Holy Grail, is revered in one of the cathedral's chapels. It has been the official chalice for many popes. This chalice with Arabic inscriptions dates from the 1st century, and was given to the cathedral by king Alfonso V of Aragon in 1436.
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.
