Medieval church dating from approx. 1250. The south chapel with the interesting frescoes is added approx. 1500. The north chapel is built 1686 and reconstructed 1785. The tower at the south chapel is built 1789. Porch, sacristy and stair tower is built in 1881-82.
The Duke to Nordborg Castle built a chapel in 1700 at the east end of the church. This chapel is the final resting place for the ducal families and their coffins are still standing in the room behind the altar. If the wooden door is closed you may open it and look through the grated door at the coffins, a list of who is laying in the coffins is found on the wooden door.
The pulpit, carved by Jørgen Ringnis is from 1626. The crucifix in the choir arc dates from approx. 1500. The altar made in 1655 is presumably from Flensburg.
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.
