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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
