Castle Caulfield is a large ruined house situated in Castlecaulfield, Northern Ireland. The house was built by Sir Toby Caulfeild between 1611 and 1619. He was granted 1000 acres during the Ulster Plantation. This land was previously owned by the O'Donnelly family, who were closely connected to the O'Neill clan in Dungannon. The O'Donnelly fort was a few miles West of the castle. There are substantial remains. The gatehouse was rebuilt at a later date, although one of the doorways may be reused.
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.
