Built in 333 BC along Gela's western coastline at Capo Soprano by the tyrant of Syracuse, Timoleon, Gela's ancient Greek fortifications are remarkably well preserved, most likely the result of being covered by sand dunes for thousands of years before their discovery in 1948. The 8m-high walls were originally built to prevent huge amounts of sand being blown into the city by the blustery sea wind. Today authorities have planted trees to act as a buffer against the encroaching sand.
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.
