Dedicated to St. Benedict of Nursia, the church of San Benedetto was built from April 1334, then it was destroyed by 1693 Sicily earthquake. The church and the monastery were rebuilt between 1708 and 1763 and Giovanni Battista Vaccarini was one of the main architects.
The church was also damaged by bombing in World War II and later restored by the architect Armand Dillon.
Its most famous feature is the Angel's Staircase, a marble entrance stair decorated with statues of angels and surrounded by a wrought iron railings. The entrance door, in wood, has panels with Stories of St. Benedict.
The interior, with a single nave, is home to frescoes by Sebastiano Lo Monaco, Giovanni Tuccari and Matteo Desiderato. The vault and semi-dome were painted Giovanni Tuccari with the History of Saint Benedict and six Allegories surrounding the Triumph of Saint Benedict. The Saint is represented in his traditional iconography, in a festive and cheerful scenario. The high altar is in polychrome marble with hardstone intarsia and bronze panels.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.
