The origins of the Maredolce Castle are unknown. Some scholars tend to attribute the foundation of the castle to the emir Ja'far al-Kalbi (998-1019), believing that it was built over a pre-existing structure. Other scholars believe that the castle dates back to the Norman era, although others consider that just the lake of the Favara Park was realized in the age of the Hauteville dynasty. The first documents regarding the castle and its park are the 'Chronicon sive Annales' of Romuald Guarna and a poem of the muslim poet Abd ar-Rahman al-Itrabanishi (12th century).
In 1071, during the military campaign to conquer Palermo, the area of the castle was occupied by the Norman Count Roger I. After a few decades, it was used as one of the Solatii Regii erected along the royal parks of the city and, thus, became one of the royal residence of the first King of Sicily, Roger II. The structure was a part of a fortified complex located at the foot of Monte Grifone, probably closed within a surrounding wall including the palace, a ḥammām and an artificial lake.
In 1328 the King Frederick III gave the castle and the park to the Teutonic Order, whose headquarters was at the Basilica della Magione. During this period the structure was used as a hospital. In the 15th century the castle passed to the noble family Beccadelli di Bologna. In 17th century another change of ownership occurred and the castle was ceded to the Duke Francesco Agraz. Under the ownership of the Agraz family the building was left in a state of massive neglect and, thus, became known with the epithet of Castellaccio.
In 1992 the Sicilian Region has acquired the complex thanks to an expropriation. The restoration started in 2007, but even in 2016 some spaces near the castle are unlawfully occupied. The still precarious conditions of the structure have temporarily prevented the inclusion of the castle within the Unesco World Heritage Site called Arab-Norman Palermo and the Cathedral Churches of Cefalù and Monreale.
By the will of Roger II, the building was surrounded by an artificial lake, at the centre of the Favara Park. The lake had at its heart an artificial island (2 hectares) and was obtained thanks to a dam interrupting the path of the source of Monte Grifone. In 16th century this source ran dry.
The building has a quadrangular drawing and is equipped with a large courtyard. Inside the castle is also present a 'palatin chapel', dedicated to the saints Philip and James.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.
