The Callanish II stone circle is one of many megalithic structures around the better-known (and larger) Callanish Stones (I) on the west coast of the isle of Lewis, in the Outer Hebrides, Scotland.
The stone circle consists of thin standing stones arranged in the shape of an ellipse measuring 21.6 by 18.9 metres. Five of the stones are standing and two have fallen. The stones vary from 2 to 3.3 metres in height. A slab, 1.4 metres, long lies in front of the western stone, pointing towards the centre of the circle. The stone circle surrounds a cairn with a diameter of 8.5 metres.
When one metre of peat was removed from the site in 1848, four holes were noticed, three grouped in an arc at the northwest, a fourth at the south-west. Wood charcoal found in them suggests that they formed an earlier timber circle about 10 metres in diameter.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.
