Iglesia Mayor de San Pedro y San Pablo is located in the center of San Fernando, opposite the Church Square. Construction of the church began in 1756, replacing the small parish church of Santa María del Castillo de San Romualdo. It was consecrated in 1764 but was not completed until the early 19th century. Its primitive design is attributed to Alejandro Perdia although Torcuato Benjumeda is credited with its final appearance. It was built to satisfy the needs of San Fernando's growing population. Financing for its construction was raised by a tax on wine. Legend states, however, that an Englishman saw the unfinished state of the church and donated a large sum of money in spite of belonging to the Anglican Church himself. Its historical value is important, as it was here that deputies of the first Spanish Constituent Assembly were sworn in on September 24, 1810. A series of small offices within the building were historically used as meeting places for some guilds.
Two architectural styles predominate the rectangular building: Late Baroque, especially the ornamental decorations around the various doors, and Neoclassicism in the upper sections of the towers topping the facade. Four bells which bear the names of the four Evangelists are situated in its two towers. The facade includes a flat bay with slightly arched lintel. The central nave is flanked by two aisles and there is a transept and a vestry which is at a slightly higher level than the rest of the church. The floor is of marble and there is an oyster stone plinth. The sacristy is behind the chancel. A hemispherical dome crowns the transept with ribbed vaults at the same height as the roof of the nave. Tuscan pillars supporting curved arches separate the aisles from the central nave.
During restoration work in 1959, the main altar was adorned with paintings of Christ crucified with St Peter and St Paul on either side. The baptismal chapel in the first section of the nave is decorated with murals of the four Evangelists, dating to 1959. Other paintings in the church include Nuestra Señora del Rosario and San Miguel. Other various works of art include Holy Week processions in the city. The crypt, known as the cellar, contains the tombs of monks.
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.
