The cathedral church of St. James the Elder is situated within the old quarter next to the city walls and in the past it could fulfil a defensive function. It was built in stages from 1380 until 1445 and finally completed in its present shape during the early 17th c. The building was erected on the rectangular plan of ceramic bricks, with nave and two aisles, hall type, without separate presbytery. Late Gothic vaulting is late 16th c. During the same time (1562-1596) the tower was added. Piotr Olszewski designed chapels flanking the tower in 1721.
The interior décor is mainly new gothic. The older elements are: in the left aisle a late Gothic triptych from early 16th c., in the right aisle the painted triptych – “Crucifixion” of 1553 in new-gothic framing. The main altar and pulpits in new-gothic style. In the baptistery chapel a Baroque 18th c. painting of the Virgin of the Rosary surrounded by St, Catherine of Siena and St. Dominique. Initially the church was a parish church of St. James the Elder, patron of the town later raised to the distinction of a joint cathedral.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.
