A motte-and-bailey castle is thought to have previously occupied the site of Llawhaden Castle and the present structure was built by the bishops of the Diocese of St David in the 13th century. The castle was abandoned in the 16th century and some of the stone was removed for local building projects. The site is privately owned by the Lord of the Manor of Llawhaden and managed by Cadw.
The remaining ruins date from the early 13th century. It is surrounded by a ditch, which was designed to be only crossable by a drawbridge. The castle is pentagonal in shape and while the north-western and western sides of the castle are no longer present, the other three sides remain. The gatehouse is located on the southern side, which is formed of two drum towers and a gateway. This was also where the drawbridge would have been located to allow entrance to the interior of the castle.
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.
