Glenveagh Castle is a large castellated mansion located in Glenveagh National Park, County Donegal, Ireland. Captain John George Adair built Glenveagh Castle between 1867 and 1873. It stands within the boundaries of Glenveagh National Park, near both Churchill and Gweedore in County Donegal, Ireland. It is built in the Scottish baronial architectural style and consists of a four-story rectangular keep, surrounded by a garden, and a backdrop of some 165.4 km2 of mountains, lakes, glens and woods complete with a herd of red deer. The Irish Gleann Bheatha (Bheithe) translates into English as 'Glen of the Birch Trees'. The visitor centre has displays that explain the park as well as an audio-visual show and is accessible for patrons with disabilities.
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.
