Tarbert Castle was a strategic royal stronghold during the Middle Ages and one of three castles at Tarbert. The castle overlooks the harbour and although pre-14th century in construction, the tower dates back to 1494 and the visit of James IV to the Western Highlands.
In 712, Tarbert was burned by King Selbach mac Ferchair of Cenél Loairn and of Dál Riata and in 731 by his son, Dúngal mac Selbaig.
King Edward II of England handed control of the castle to the Scottish King John II de Balliol in 1292. A fortified structure was built in Tarbert during the 13th century. It was reinforced with the addition of an outer bailey and towers in the 1320s by Robert the Bruce, to protect it against the Lords of the Isles. A towerhouse was added in the 16th century, which is the most noticeable part of the remains. The castle occupies high land above the village, providing views up Loch Fyne and beyond to the Firth of Clyde. This castle was captured from John MacDonald of Islay, Lord of the Isles by James IV of Scotland as part of his campaign to destroy the power of the Lords of the Isles in 1494. In 1687 the castle was involved in another skirmish when Walter Campbell of Skipness Castle seized it as a stronghold for Archibald Campbell, 9th Earl of Argyll as part of actions in support of the Monmouth Rebellion in England.
There are only a couple of standing walls left and they are considered unstable. The castle has a very commanding view of the water approaches.
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.
