The temple of Augustus is the centre of an imperial cult complex, the "Sebasteion".
The temple was built at the highest point of the city. It has the shape of a rectangle with a semicircular back. The temple was built in the middle of the semicircle. It was to be seen from large parts of the city and the fertile surrounding countryside. The cult complex surrounding it was surrounded on all sides by porticoes. One entered the complex through an elaborately designed propylon.

Most of the temple has been destroyed. The existing remains of the substructure, the stylobate and fragments were sufficient to reconstruct the temple. The 13.6 x 23.5 m temple was built on a 14.2 x 27.95 m and 2.6 m high substructure. A twelve-step staircase led into the vestibule. Below the cella was a 4.5 x 7.75 m and 2.5 m deep cellar vault.

Augustus (* 23. September 63 B.C. as Gaius Octavius; † 19. August 14 A.D.) was the first Roman emperor. Gaius Iulius Caesars, grand nephew and principal heir, won the power struggles that followed his assassination in 44 B.C. and was the sole ruler of the Roman Empire from 31 B.C. to 14 AD.
Under the motto of the restoration of the republic - restitutio rei publicae - he in reality pursued its permanent transformation into a monarchy in the form of a principality. Thus he put an end to the century of Roman civil wars and founded the Julian-Claudian imperial dynasty. His rule, outwardly marked by numerous expansion wars, led to a long lasting phase of consolidation and peace, which was glorified as Pax Augusta.
