St Martin's Church (Sankt Mortens Kirke) is one of the city's medieval churches. Known from records since approximately 1280, it is believed to have been built and put into service around 1200. The building was constructed as the city's parish church. It is dedicated to St Martin of Tours considered its patron saint.
The church is a Gothic structure built with bricks. The oldest parts of the church are from the 1220s. The tower was added in the 15th century but the baptismal chapel and the porch were completed as late as the 1850s.
The arches bear a portrait of St Martin. There are many frescoes of the period; one depicts him as a soldier sitting on his horse, while he cuts a piece of his officer cap and gives it to a beggar. The church's first organ, installed in 1587, was made by Hans Brebus (d. 1603), a Flemish organ builder who practiced in Denmark and Sweden. The altarpiece (1667) of 6m height is decorated with figures wearing grotesque masks or with mustaches, some of whom are stooping low) and is attributed to thewoodcarver Abel Schrøder (1602-1676) who was also the church's organist for forty-two years. Today's Frobenius organ dates to 1975. The pulpit was built by Abel Schrøder's father.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.
