Penstowe Castle, also called Kilkhampton Castle, was a medieval fortification built near Kilkhampton, Cornwall, possibly during the years of the civil war in the 12th century known as the Anarchy.
The precise date of Penstowe Castle's construction is uncertain, but it was built during the years of the Anarchy in the mid-12th century, either by Robert, 1st Earl of Gloucester, feudal baron of Gloucester, who was certainly the tenant-in-chief of the manor of Kilkhampton, or by his tenants and relatives the Grenville family (possibly Sir Richard I de Grenville (d.post 1142) of Neath Castle, Glamorgan), which held the manor of Kilkhampton and the manor of Bideford in Devon from the Honour of Gloucester. Stowe House was the Grenvilles' residence at Kilkhampton, demolished and rebuilt in grand form in 1679 by John Granville, 1st Earl of Bath (1628-1701).
Kilkhampton Castle was built to a motte and bailey design, positioned on a knoll and protected by steep slopes on the north and south sides. The motte today is shaped as an oval, 18 metres by 8 metres. The configuration of baileys is unusual, although similar to nearby Eastleigh Berries Castle. A D-shaped building was located on top of the motte.
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.
