Ekebyholm is a castle-like mansion and a former manor located by Lake Syningen in Rimbo parish in Norrtälje Municipality in Stockholm county, Sweden. In 1932, the Adventist school purchased Ekebyholm. Presently Ekebyholmsskolan is located on site.
Ekebyholm in Rimbo (currently a part of Norrtälje) was attached with the estate of Mörby, owned by the Pomeranian-originated family of Slaveka. Bengt Gabrielson (Oxenstierna) af Mörby (d. 1591) acquired the estates of Mörby and Ekebyholm which were separated with Mörby passing to his elder son Gabriel Bengtsson Oxenstierna (1586-1656) and Ekebyholm passing to the youngest, posthumous son Bengt Bengtson Oxenstierna (1591-1643) who first had the manor built at Ekebyholm.
The current appearance was built by Arvid Horn during the 18th century.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.
