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:Monte d"Accoddi is a Neolithic archaeological site in northern Sardinia, located in the territory of Sassari. The site consists of a massive raised stone platform thought to have been an altar. It was constructed by the Ozieri culture or earlier, with the oldest parts dated to around 4,000–3,650 BC.
The site was discovered in 1954 in a field owned by the Segni family. No chambers or entrances to the mound have been found, leading to the presumption it was an altar, a temple or a step pyramid. It may have also served an observational function, as its square plan is coordinated with the cardinal points of the compass.
The initial Ozieri structure was abandoned or destroyed around 3000 BC, with traces of fire found in the archeological evidence. Around 2800 BC the remains of the original structure were completely covered with a layered mixture of earth and stone, and large blocks of limestone were then applied to establish a second platform, truncated by a step pyramid (36 m × 29 m, about 10 m in height), accessible by means of a second ramp, 42 m long, built over the older one. This second temple resembles contemporary Mesopotamian ziggurats, and is attributed to the Abealzu-Filigosa culture.
Archeological excavations from the chalcolithic Abealzu-Filigosa layers indicate the Monte d"Accoddi was used for animal sacrifice, with the remains of sheep, cattle, and swine recovered in near equal proportions. It is among the earliest known sacrificial sites in Western Europe.
The site appears to have been abandoned again around 1800 BC, at the onset of the Nuragic age.
The monument was partially reconstructed during the 1980s. It is open to the public and accessible by the old route of SS131 highway, near the hamlet of Ottava. It is 14,9 km from Sassari and 45 km from Alghero. There is no public transportation to the site. The opening times vary throughout the year.
