The Roman Theatre in Aosta was built in the late reign of Augustus, some decades after the foundation of the city (25 BC), as testified by the presence of pre-existing structures in the area. There was also an amphitheatre, built during the reign of Claudius, located nearby.
The theatre occupies three blocks annexed to the ancient city walls, along the Roman main road (the decumanus maximus, next to the Porta Praetoria. The structure occupied an area of 81 x 64 m, and could contain up to 3,500/4,000 spectators.
What remains today include the southern façade, standing at 22 m. The cavea was enclosed in a rectangular-shaped wall including the remaining southern part. This was reinforced by buttresses each 5.5 m from the other, and included by four orders of arcades which lightened its structure. It has been supposed that the theatre once had an upper cover, in the same way of the Theatre of Pompey in Rome.
The orchestra had a diameter of 10 m. The scene, of which only the foundations remain, was decorated by Corinthian columns and statues, and was covered with marble slabs.
A marketplace surrounded by storehouses on three sides with a temple in the centre with two on the open (south) side, as well as a thermae, also have been discovered.
Since 2011, the theatre is used for music shows and theatrical performs.
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.
