The city's name derives from the Arabic 'qal'at-al-jarar' ('Castle of jars') – a name that attests to the antiquity of the pottery works which are still thriving. It has been inhabited since prehistoric times, as shown by the presence of two necropoleis dating from the second millennium BCE and by numerous other archaeological finds. It was later inhabited by the Sicels pre-Roman population.
The Arabs built a castle here that in 1030 was attacked by Ligurian troops under the Byzantine general George Maniakes, who have left traces of Ligurian language in the current dialect. The city flourished under the Norman and Hohenstaufen domination, becoming a renowned center for production of ceramics.
Caltagirone was almost completely destroyed by the earthquake of 1693. Many public and private buildings have then been reconstructed in earthquake Baroque style. Primarily for this reason the city has been included, together with the surrounding territory, in an area protected by the UNESCO World Heritage program.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.
