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:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
