It is the most complete copy of Res Gestae Divi Augusti that has survived to the present day, even as the original in Rome had disappeared.

[1] The Augusteum was built between 25–20 BC after the conquest of central Anatolia by the Roman Empire and the formation of the Galatia province, with Ancyra as its administrative capital.

It was reintroduced to the western world by Antun Vrančić, ambassador of Ferdinand of Austria, to the Sultan Suleyman the Magnificent (1555–1562) at Amasia in Asia Minor.

Only the side walls and the ornamented door frame remain; the positions of six columns can still be recognized.

After the fair, it was put in storage until it was displayed at the Mostra Augustea della Romanità in 1937.
