The Basilica of Saint Severinus is built upon a Christian necropolis dating to the 4th century CE. The epitaph of Flavinus was engraved beneath a representation of a chrism on the lid of a sarcophagus dating to between 365 and 385 CE, testifying to the Christian presence in Bordeaux to Late Antiquity. Today, it is housed in the Museum of Aquitaine in Bordeaux.
At the beginning of the 11th century, the canons of the basilica decided to commence a major reconstruction. It has the shape of a robust Romanesque church in the basilical form. During the course of the 11th through 13th centuries the nave and the choir were built. In the 13th century, the canons ordered the construction of the southern entry which is surmounted by a porch with a belfry built in the Renaissance style. The entrance consists of a large bay flanked by two blind arches and is decorated with fourteen carved statues representing the twelve apostles and two female statues representing the Synagogue and the Church. The church has three tympana: the main one is decorated with scenes from the Resurrection and the Judgement; the left has a representation of the holy women who visited the tomb; and the right depicts the arrival of Saint Severinus according to Saint Amand's dream. The five-sided porch that leads to it was built later.
The 14th and 15th centuries mark the construction of several chapels. One of them was the Chapel of Madonna of the Rose which was dedicated to the Virgin. It contains an altar that was consecrated by Archbishop Pey Berland in 1444. It was designed in the flamboyant Gothic architecture reminiscent of that found in late-15th-century Normandy and England.
Twice in 1566 and 1698, parts of the church's vault structure collapsed causing serious damage. At the beginning of the 18th century, the architect Jean-Baptiste Augier was charged with rebuilding and bracing them with pillars equipped with stone belt courses.
The basilica has benefited from restoration in recent decades. The roofs were redone, as were upper parts of the basilica. The chapels of Madonna of the Rose and Saint John as well as choir were restored. The church is then inscribed as a UNESCO World Heritage Site in 1998 due to it being the head of one of the Ways of Saint James of Compostela.
The church has retained an ornate 15th-century episcopal pulpit that still has its armrests, backrest and dais. This is a very significant item as it is reserved for the new archbishop of Bordeaux who must take an oath on the relics of Saint Severinus before he is nominated.
The choir still houses thirty-two of the forty-seven stalls from the 15th century. These stalls were intended for the chapter. They are decorated with images of saints, prophets and satirical scenes.
The Basilica of Saint Severinus has a number of well-maintained medieval statues. Among them, are the 13th-century Our Lady of Glad Tidings, the 14th-century alabaster Madonna of the Rose and one of Saint Martial.
The ancient crypt houses sepulchres of the Merovingian family.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.
