Casmenae or Kasmenai was an ancient Greek colony located on the Hyblaean Mountains, founded in 644 BC by the Syracusans at a strategic position for the control of central Sicily. It was also intended as a military forward-position on the Via Selinuntina road that connected Syracuse to Akragas (modern-day Agrigento) - also on that road were Gela and Akrillai to Casmene's west and Akrai to its east. Destroyed by the Romans in 212 BC, Casmene was abandoned during the 3rd century BC and never inhabited again.
The site was discovered by the Sicilian archeologist Paolo Orsi during the first half of the 20th century, after he had identified the most probably site at Monte Casale in Buscemi at 830m above sea level, on an extinct volcano near Monte Lauro, 7 km from Giarratana and 12 km from Palazzolo Acreide. Remains of the defensive walls, long 3.400m, are still visible with the base of one of the temples and some dwellings.
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.
