The Mausoleum of Augustus is a large tomb built by the Roman Emperor Augustus in 28 BC. The interior of the mausoleum is not open to tourists. The mausoleum was one of the first projects initiated by Augustus in the City of Rome following his victory at the Battle of Actium in 31 BC. The mausoleum was circular in plan, consisting of several concentric rings of earth and brick, planted with cypresses on top of the building and capped by a conical roof and a statue of Augustus. Vaults held up the roof and opened up the burial spaces below.
In the Middle Ages the tumulus was fortified as a castle and occupied by the Colonna family. After the disastrous defeat of the Commune of Rome at the hands of the Count of Tusculum in 1167, the Colonna were disgraced and banished, and their fortification in the Campo was dismantled. Thus it became a ruin.
It was not until the 1930s that the site was opened as a preserved archaeological landmark along with the newly moved and reconstructed Ara Pacis nearby. The restoration of the Mausoleum of Augustus to a place of prominence featured in Benito Mussolini's ambitious reordering of the city of Rome which strove to connect the aspirations of Italian Fascism with the former glories of the Roman Empire.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
