Swansea Castle is located in the city centre of Swansea. It was founded by Henry de Beaumont in 1107 as the caput of the lordship of Gower. A timber castle existed in Swansea in 1116, when it was recorded as being attacked by Welsh forces who destroyed the outer defences. The castle was besieged in 1192 by Rhys ap Gruffydd, Prince of Deheubarth. Despite 10 weeks of starvation the castle was saved.
After various other unsuccessful attacks the castle fell in 1217 but was restored to the English in 1220 as part of the settlement between Llywelyn ap Iorwerth and Henry III of England. The castle was rebuilt in stone, probably between 1221 and 1284, firstly the inner castle with at least one tower, finally the large outer bailey.
By the 14th century the castle was losing its military importance. The castle owners were subsequently absentee landlords. By the 1670s the square tower was being used as a bottle factory and, in 1700, a town hall was built in the castle courtyard. By the mid 1700s the Great Hall had become Swansea's workhouse. The town hall was replaced by a post office in the 1800s and, by 1850, a military Drill Room had replaced the workhouse.
Part of the interior of the castle, in particular the large motte, was demolished 1909–1913 for the construction of a newspaper office. In the very early 1930s, poet Dylan Thomas worked for the South Wales Daily Post at the castle site. The newspaper offices were removed in 1976 and the remains of the castle were later consolidated and opened up to view from the street.
The only visible remains today, two sides of the rectangular South East corner of the outer bailey, were built in the late 13th or early 14th century. The south face (which ends in a tall garderobe tower) is capped with an elegant series of arcades at the wall-head.
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.
