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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
