Peniscola Castle is situated on a crag overlooking the Mediterranean Sea. Arab writer Al-Idrisi described Baniskula in the 11th century AD, and briefly described a Moorish castle overlooking the sea. There are no detailed descriptions until the 13th century, when James I of Aragon briefly summarised the Muslim defences. The castle was transferred to James's control in 1229.
The current form of the castle is essentially that developed by the Knights Templar, who planned to develop a kingdom centered on Peniscola. James II of Aragon gave the castle to the Templars in 1294. The Templars began work that year, demolished the Muslim fortifications, and completely rebuilt the castle; the work was completed in 1307. In common with other Templar fortifications, the castle was laid out around an inner ward and possessed a chapel. Architectural features included barrel vaulting and round arches. The basic Templar core of the castle remains intact; some changes were made by Antipope Benedict XIII in order to modify it for use as a papal residence in the early 15th century. The castle defences and the associated town fortifications were significantly upgraded from the early 16th century onward, in line with advances in military technology. The castle was massively redeveloped by military engineer Giovanni Battista Antonelli in the 16th century.
The castle was involved in various military conflicts of the Kingdom of Aragon, and later in the War of the Spanish Succession in the early 18th century, the Peninsula War and civil conflicts in the early 19th century, each of which impacted upon the state of the castle defences in some form. The castle garrison was finally disbanded in 1890.
The castle where Benedict lived from 1417 until his death in 1423 was restored, improved and new walls were added in 1960 when Anthony Mann's film El Cid was partially filmed there. The town and castle of Peníscola played the role of Valencia. The castle is now a popular tourist attraction and the beaches and surrounding area are a popular family holiday resort.
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.
