St Elidyr's Church was the principal place of worship of the Cawdor family, former owners of the Stackpole Estate. The church has medieval origins, but most of the original structure, apart from the 12th or 13th century tower and part of the chancel, has been absorbed into later additions and renovations.
The church is built on a slope in a wooded valley, the slope partly excavated to accommodate the building. Cruciform in plan, the chancel is about 6.5 metres long by 4.5 metres wide. There are north and south transepts, a vestry and a chapel. There is an open porch to the south, within which there is an early medieval inscribed stone. There was a crypt beneath the chancel, now filled in. The roof is slate, and there is a wrought iron cross at its eastern end. The altar table is oak, as are the communion rails.
The tower is a prominent feature and an older part of the church. It is of a typical local design with a parapet, but unusually slender. The lowest storey has a vault opening into the north transept. Two upper floors and the roof are crudely constructed. Each storey has windows or louvred openings, the lowest being blocked. The top storey has louvred openings on all four sides and there is a spiral staircase.
A stone cross with a modern head stands in the churchyard.
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.
