Avignon Cathedral is the seat of the Archbishop. The cathedral is a Romanesque building, built primarily in the second half of the 12th century. The bell tower collapsed in 1405 and was rebuilt in 1425. In 1670-1672 the apse was rebuilt and extended.
The building was abandoned and allowed to deteriorate during the Revolution, but it was reconsecrated in 1822 and restored by the archbishop Célestin Dupont in 1835-1842. The most prominent feature of the cathedral is a gilded statue of the Virgin Mary atop the bell tower which was erected in 1859.
The interior contains many works of art. The most famous of these is the mausoleum of Pope John XXII (died 1334), a 14th-century Gothic carving. It was moved in 1759, damaged during the Revolution, and restored to its original position in 1840. The cathedral was listed as a Monument historique in 1840.
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.
