Tintagel Castle is a medieval fortification located on the peninsula of Tintagel Island adjacent to the village of Tintagel, North Cornwall. The site was possibly occupied in the Romano-British period, as an array of artefacts dating from this period have been found on the peninsula, but as yet no Roman-era structure has been proven to have existed there. It was settled during the early medieval period, when it was probably one of the seasonal residences of the regional king of Dumnonia. A castle was built on the site by Richard, 1st Earl of Cornwall in the 13th century, during the High Middle Ages. It later fell into disrepair and ruin.
In the 1930s, excavations revealed significant traces of a much earlier high status settlement, which had trading links with the Mediterranean world during the Late Roman period. Later digs uncovered the outlines of a palace from the 5th or early 6th century (the early medieval period), with evidence of writing and of articles brought in from Spain and from the eastern end of the Mediterranean Sea.
The castle has a long association with legends related to King Arthur. This was first recorded in the 12th century when Geoffrey of Monmouth described Tintagel as the place of Arthur's conception in his mythological account of British history, Historia Regum Britanniae. Geoffrey told the story that Arthur's father, King Uther Pendragon, was disguised by Merlin's sorcery to look like Gorlois, Duke of Cornwall, the husband of Igraine, Arthur's mother.
The castle was built on the site by Earl Richard in 1233 to establish a connection with the Arthurian legends that were associated by Geoffrey of Monmouth with the area and because it was seen as the traditional place for Cornish kings.
Tintagel Castle has been a tourist destination since the mid-19th century. Owned by William, Prince of Wales as part of the landholdings of the Duchy of Cornwall, the site is managed by English Heritage.
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.
