The temple of Rome and Augustus was erected in the late first century BC. Several architectural elements of the building were found east of the Parthenon and many more were brought here after their discovery elsewhere. Nearby are the irregular tufa foundations (approximately 10.50x13 metres) of a building generally considered to be the Roman temple. Another theory, however, based on the construction technique of these foundations and on depictions of the Acropolis on Roman coins, places the temple east of the Erechtheion.
A small, round edifice, about 23 meters from the Parthenon, was to be the last significant ancient construction on the summit of the rock.
The inscription on the temple's epistyle mentions that the building was dedicated by the city of Athens to the goddess Rome and to Octavian Augustus. Pausanias does not mention the building during his visit to the Acropolis, possibly because it did not present any interest at his time. The small, circular temple had a single row of nine Ionic columns and no interior wall, the entablature and conical roof being entirely of white marble. The fact that the columns imitate those of the Erechtheion may indicate that the temple was built by the same architect who repaired the Erechtheion after it was damaged by fire.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
