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.
The Externsteine (Extern stones) is a distinctive sandstone rock formation located in the Teutoburg Forest, near the town of Horn-Bad Meinberg. The formation is a tor consisting of several tall, narrow columns of rock which rise abruptly from the surrounding wooded hills. Archaeological excavations have yielded some Upper Paleolithic stone tools dating to about 10,700 BC from 9,600 BC.
In a popular tradition going back to an idea proposed to Hermann Hamelmann in 1564, the Externsteine are identified as a sacred site of the pagan Saxons, and the location of the Irminsul (sacral pillar-like object in German paganism) idol reportedly destroyed by Charlemagne; there is however no archaeological evidence that would confirm the site's use during the relevant period.
The stones were used as the site of a hermitage in the Middle Ages, and by at least the high medieval period were the site of a Christian chapel. The Externsteine relief is a medieval depiction of the Descent from the Cross. It remains controversial whether the site was already used for Christian worship in the 8th to early 10th centuries.
The Externsteine gained prominence when Völkisch and nationalistic scholars took an interest in the late 19th and early 20th centuries. This interest peaked under the Nazi regime, when the Externsteine became a focus of nazi propaganda. Today, they remain a popular tourist destination and also continue to attract Neo-Pagans and Neo-Nazis.
