The Cathedral of Burgo de Osma is in the Gothic architectural style, and was constructed on an area previously occupied by a Romanesque church. It is one of the best preserved medieval buildings in the country and considered one of the best examples of thirteenth-century gothic architecture in Spain. The building of the church started in 1232, and was completed in 1784. The cloister is from 1512. The tower is from 1739. The cathedral is dedicated to the Assumption of Mary.
The latest additions are from the 18th century although the cathedral was built over a primitive 13th-century Romanesque temple, reason why there are so many interesting elements to see such as the main façade and its Renaissance-style door, its high tower, the altarpiece and the Gothic marble pulpit in the major chapel. Other works of art are the frescos in the dome, the Immaculate figure on the central altar which was brought from Rome, the Neoclassical sacristy, the Flamboyant Gothic cloister, beautiful stain glass windows on the upper part of the cathedral or the tomb of San Pedro de Osma, which is considered a masterpiece of funerary art. Inside the cathedral, there is also a museum with paintings and sculptures, as well as valuable codices such as the one known as “El Beato”.
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.
