Agilkia Island in the reservoir of the Old Aswan Dam along the Nile River is the present site of the relocated ancient Egyptian temple complex of Philae. Partially to completely flooded by the old dam's construction in 1902, the Philae complex was dismantled and relocated to Agilkia island, as part of a wider UNESCO project related to the 1960s construction of the Aswan High Dam and the eventual flooding of many sites posed by its large reservoir upstream. To allow Agilkia island to accominate the relocated temple, the island was leveled to match the old contours of Philae island as best as possible, which required the removal of the top of the island.
The most ancient was a temple for Isis, built in the reign of Nectanebo I during 380–362 BC, which was approached from the river through a double colonnade. Nekhtnebef was his ancient Egyptian royal titulary and he became the founding pharaoh of the Thirtieth and last native dynasty when he deposed and killed Nepherites II.
For the most part, the other ruins date from the Ptolemaic Kingdom, more especially with the reigns of Ptolemy II Philadelphus, Ptolemy V Epiphanes, and Ptolemy VI Philometor (282–145 BC), with many traces of Roman work in Philae dedicated to Ammon-Osiris.
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.
