The Chiesa degli Ottimati history is documented as early as the 10th century. The present name derives from a Norman confraternity that rebuilt the church, and dedicated it to the Virgin of the Annunciation. The Ottimati were a congregation of nobles founded by the Normans. Over time, these included the Filocamo, Griso, Altavilla and Borboni.
The original layout appears to have been a Greek cross, with multiple domes. The Normans under Roger II, built a church on top, eliminating many of the domes. On September 3, 1594 the church was damaged and burned during a sack of the town by Saracen raiders. In 1597, the church commissioned a new painting of the Annunciation by Agostino Ciampelli.
By the 18th century, the church was affiliated with the Jesuits, and a school was adjacent. With the suppression of the Jesuits in 1767, the church fell empty. It was damaged by earthquakes in 1783 and 1908. The church rebuilt after 1908 moved from the original location, and was completed in 1933, using a design by Pompilio Seno, who adopted a neo-Byzantine style with Arab-Norman elements. Some elements from the destroyed Norman basilica of Santa Maria di Terreti were used.
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.
