The oldest recorded mention of the place (Feyena) has been dated to 1325. At this time, there was a fortified manor or a castle at the site, the remains of which were reconstructed and expanded in a romantic fashion during the 19th century but are still visible in the manor park.
The present manor house was commissioned by the Baltic German von Stackelberg family and built 1784-1797. It was designed by an anonymous Italian architect in latebaroque style. The wings of the long main house have circular pavilions with preserved decorated vaulted roofs, where formerly the family displayed their art collection, which reputedly held works by Hans Holbein, Nicolas Poussin, Claude Lorrain and Antoine Watteau . The main building also showcases some preserved architectural details, notably two painted ceilings as well as further, albeit later, architectural details.
The most famous resident of the manor house was the archaeologist Otto Magnus von Stackelberg who grew up there. Nowadays the manor houses an elementary school (est. 1855), a public library and a public Internet point of access.
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.
