St. Nicholas' Church (Niguliste kirik) is a medieval church in Tallinn. The church is dedicated to Saint Nicholas, the patron of the fishermen and sailors. It was founded and built around 1230-1275 by Westphalian merchants, who came from Gotland in the 13th century. While the city was still unfortified, the church had heavy bars for closing the entrances, loopholes and hiding places for refugees. When the fortifications around Tallinn were finished in the 14th century (the town wall enclosed the church and the settlement in 1310), the St. Nicholas' Church lost its defensive function and became a typical medieval parish church. There are only a few parts of the original church that have been preserved through the present.
In 1405–1420 St. Nicholas' church obtained its current appearance, when the central aisle was built higher than side aisles and the church was redesigned as a full basilica. In 1515 the tower was built higher and covered with late-Gothic spire. In late 17th century the tower was strengthened and secured. The spire was replaced with a Baroque spire with airy galleries, which was raised higher stage by stage through several centuries. The tower is now 105 metres high.
Saint Nicholas was the only church in Tallinn which remained untouched by iconoclasm brought by the Protestant Reformation in 1523 (or 1524). The head of the congregation poured molten lead into the locks of the church, and the raging hordes could not get in.
The church was partially destroyed in Soviet Bombing of Tallinn in World War II. After restoration it is in use as an art museum and concert hall. Most famous of the artworks is a painting Danse Macabre (Dance of Death) by the Lübeck master Bernt Notke, which depicts the transience of life, the skeletal figures of Death taking along the mighty as well as the feeble ones. Only the initial fragment of the original 30 metres (98.4 ft) wide painting (accomplished at the end of the 15th century) can be seen in the St Nicholas' Church.
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.
