Sundrum Castle is located 1.5 kilometres north of Coylton. It was originally built in the 14th century for Sir Duncan Wallace, Sheriff of Ayr, and considered one of the oldest inhabited castles in Scotland. Long-term owners included the Cathcart family, and the Hamilton family, who expanded it the 1790s, incorporating the original keep into a mansion.
It was further expanded in the early 20th century by Earnest Coats. For a time it was then a hotel, though fell into disrepair. After extensive renovations in the 1990s, it was split into multiple privately owned properties. The Sundrum estate now also includes a holiday park.
The castle is split into three separate properties, consisting of the original tower keep, and separate Georgian and Victorian wings, each with their own style.
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.
