In the Middle Ages the Vaeggerløse church was dedicated to St Olaf. The chancel and nave from the late Romanesque period were built in brick on a profiled plinth with pilaster strips on the corners. The chancel's pilaster strips now only remain on its southwest corner. Originally there was also an apse which was torn down but later replaced during the restoration work in 1861 by the Hamburg architect Ernst Heinrich Glüer. On that occasion, the south door was bricked up but the door frame remains. The tower is from the Late Gothic period.
The chancel and the nave have a flat-beamed ceiling. The altarpiece painting of Christ Resurrected is by Heinrich Hoffman (1868). The pulpit from c. 1640 is the work of Jørgen Ringnis, similar to that in Aastrup Church. Its large shell-framed panels depict the four evangelists. The Early Gothic crucifix on the north wall of the nave, c. 175 cm high, is from the late 13th century.
In 1906, frescos from c. 1520 were discovered in the tower vault. Painted on a thin layer of whitewash, they were in poor condition. The south segment depicted the Adoration of the Magi, the fresco on the east segment could not be identified and that on the north side showed Christ's entry into Jerusalem followed by haloed apostles. The fresco on the west segment, depicting a lively scene of the Supper at Emmaus, was in good enough condition to be preserved. Christ sits with two distinguished gentlemen at a finely set table with bread and a spotted leg of venison. There are two servants, one carrying a bowl, the other pouring wine from a jug. The woman lying on the floor in the foreground is perhaps Mary Magdelene. The colours are grey, russet, ochre and green.
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.
