The Greek theatre of Syracuse lies on the south slopes of the Temenite hill, overlooking the modern city of Syracuse. It was first built in the 5th century BC, rebuilt in the 3rd century BC and renovated again in the Roman period. Today, it is a part of the Unesco World Heritage Site of 'Syracuse and the Rocky Necropolis of Pantalica'.
It seems that the theatre was renovated in the third century, transforming it into the form seen today. Its structure was extended, taking into account the shape of the Temenite hill and the best possibilities for acoustics. Another typical characteristic of Greek theatres is the celebration of the panoramic view, also applied to the theatre of Syracuse, offering a view of the bay of the port and the island of Ortygia.
During the Roman era, important modifications were made to the theatre, perhaps at the time when the colonia was founded in the early Augustan period. The cavea was modified to a semicircular form, typical of Roman theatres, rather than the horseshoe used in Greek theatres and corridors allowing access past the scene building (parodoi). The scene building itself was reconstructed in monumental form with rectangular niches at centre and two niches with a semicircular plan on the sides, containing doors to the scene.
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.
