Audley's Castle is a three-storey tower house named after its 16th century owner, John Audley.
There are thousands of small stone towers similar to Audley's Castle in the Irish countryside. They are one of the commonest of archaeological sites, which indicates these were not buildings put up for the higher aristocracy, but for lesser lords and gentry. Most were built in the late Middle Ages (roughly 1350–1550). Audley's was built towards the end of this period.
There is very little historical information about the buildings in the small courtyard around Audley's. Only a minority of towers had courtyard walls at all, and their buildings were clearly less important than the tower. The towers in different parts of the country vary, with distinct regional patterns. Audley's with its two turrets linked by an arch is one of a type found in County Down only.
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.
