St. Peter and St. Paul's Cathedral is the cathedral church of the Roman Catholic Apostolic Administration of Estonia. Catholicism was introduced to Estonia by force via the Northern crusades and dominated religious life during the Middle Ages. However, following the Reformation during the 16th century, Lutheranism took its place as the dominant faith, and during the time of Swedish rule in Estonia, Catholicism was banned.
Following Sweden's loss of Estonia to the Russian Empire during the Great Northern War, religious freedom was introduced by the new authorities. In 1799, the Catholic parish had grown large enough to be granted the former refectory of the long-since closed St. Catherine's Monastery as a place of worship on the site of the present church. In 1841, designs were made for a proper new church building for the site, which had grown too small. The architect was the well-known St. Petersburg architect Carlo Rossi. He designed a neo-Gothic basilica, without an apse, with a neo-classical exterior.
Between 1920 and 1924, the main, western façade received its present look, a work by architects Erich Jacoby and Franz de Vries somewhat deviating from Rossi's original façade. The interior of the church still reflects Rossi's design, however the wooden, neo-Gothic decoration has been removed. The cathedral has undergone a series of renovations, the latest in 2002–2003.
The cathedral incorporates several works of art, including works by local Baltic German artists Carl Sigismund Walther, Robert Salemann and a copy of a painting by Guido Reni.
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.
