Loughor Castle is a ruined, medieval fortification built around 1106 by the Anglo-Norman lord Henry de Beaumont, during the Norman invasion of Wales. The site overlooked the River Loughor and controlled a strategic road and ford running across the Gower Peninsula. The castle was designed as an oval ringwork, probably topped by wicker fence defences, and reused the remains of the former Roman fort of Leucarum.
Over the next two centuries, the castle was involved in many conflicts. It was attacked and burnt, probably in the Welsh uprising of 1151, and was captured by the forces of Llywelyn the Great in 1215. John de Braose acquired the castle in 1220 and repaired it, constructing a stone curtain wall to replace the older defences. Attacked again in 1251, the castle was reinforced with a stone tower in the second half of the 13th century. It declined in importance during the late-medieval period, and by the 19th century, the castle was ruinous and overgrown with ivy.
In the 21st century, Loughor Castle is controlled by the Welsh heritage agency Cadw and operated as a tourist attraction. The ruined tower and fragments of the curtain wall still survive on top of the ringwork's earthwork defences, which now resemble a motte, or mound, and are part of the Loughor Castle Park.
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.
