Fort de la Conchée is an island fortification constructed by Sebastien Vauban. In 1689 Vauban conducted an inspections of French coastal fortifications for King Louis XIV, who wished to strengthen and improve the country's defences. In 1693 whilst the fort was being constructed the English raided the town. They landed on Conchée where they slighted the works and captured those working on the fort.
Again in 1695 the English, with their Dutch allies, attacked the fortress. Though the fort was unfinished, ten guns had been installed, which permitted the French to repulse the attack. The battery then turned its guns on the main attacking fleet causing much damage to it. The fort was finally finished in 1705. The fortress was demilitarised in 1901.
During the Second World war the Germans used the abandoned fort for target practice. The Allies then attacked the fort during St Malo's liberation.
The fort covers almost the entire island. The fortress consists of a granite two-storey structure, with an upper terrace for the fort's armament.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.
