Kerelaw Castle is said to have been held by the Lockharts from Richard de Morville, Constable of Scotland, as far back as 1191, after Stephen Lockhart or Loccard obtained a grant of land in Ayrshire. The castle and barony were eventually passed on to the Campbells of Loudoun and later to the Cunninghames (or Cunninghams/Cuninghames) of Kilmaurs. It was in the Cunninghame's possession in 1488 that the castle was sacked and burned by the 2nd Lord Montgomerie, during the well documented and long-term feud between these two prominent Ayrshire families.
Kerelaw was rebuilt sometime after 1488 and is reported to have contained a number of carved coats of arms of the Scottish nobility, taken from Kilwinning Abbey, Nine fishermen from Saltcoats were granted leases in 1545 in return for carrying the Earl's furniture to Finlayston on the Clyde every spring from the Creek of Saltcoats and bringing it back again in the autumn when the family returned to Kerelaw for the winter months. A half barrel of herrings was also to be furnished yearly to the Earl.
Kerelaw Castle is now a ruin, with three walls surviving in various states of decay. Gothic windows still adorn the southern wall, believed to have been inspired by those at Kilwinning Abbey.
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.
