Château de Hierges is a partially ruined castle. The castle, originally called Château de Jerusalem (Castle of Jerusalem) was built on the site of a castrum whose origins date back to the 9th century, when the seigneurie of Hierges was part of the property of the house of Ardenne. At the time of the Crusades, the fortress of Hierges was given to the Prince-Bishopric of Liège and, in the 12th century, the castle was destroyed.
The castle was rebuilt in the 16th century, starting in 1560, with more comfort and openings for firearms. In the 18th century the former common and the dovecote were added. The castle was assaulted by revolutionaries in 1792 and destroyed by fire on 18 November 1793.
Of this Meuse-style Renaissance castle, there remain the curtain walls and three large round partially ruined towers, constructed in red brick and blue stone. The fourth covered tower, semi-circular in blue stone from Givet, is inhabited by the current owner.
On the towers, gun emplacements provided for mutual defence by cross fire. Some windows have cross mullions.
The exterior gardens have been restored to present the appearance they would have had during the Renaissance.
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.
