Panagia Eleousa church dates to the 16th century, and is two aisled, rather than the three which would be more normal for the style of the time. The aisles end in a pair of cylindrical apses. Outside the church are the remains of the monastery which this church once served.
The two aisles are separated by a double archway, with the northern aisle being much smaller than the southern one. This difference in size can also be noticed from the outside in the different dimensions of the windows at the eastern end. The whole of the western end is a later addition, and the join can be seen both externally and internally.
The main door of the church shows Lusignan influences, which explains the lopsided nature of the church. The French Lusignans were Latin Christians, and while not actually banning Orthodox Christianity, treated it as second class. There are other examples in the Middle East where the ruling classes reluctantly allowed the peasants space to worship in their churches. To remind them of their place, the space allocated to the Orthodox Christians was much smaller than that allocated to the Latin Christians.
Although disused, the church continues to be a place of pilgrimage by Orthodox visitors, and it is unusual to visit and not see a lit candle.
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.
