Knutby church is a medieval stone church built probably in the late 13th century. The sacristy was built during the 1300s or 1400s. The porch was added probably in the 1400s. The nave, together with the tall and wide chancel is covered by a single pitched roof. The interior is richly decorated with murals, more than any other of Uppland churches.
Albertus Pictor was the author of the younger paintings depicting the life of Jesus with Old Testament features. The main restoration was made in 1925 and unveiled paintings and furnishings were restored to their original color scheme from the 1700s.
There are several medieval artifacts. The font, made of Gotland limestone, was made between 1250-1300. The triumphal crucifix date back to the 1200’s and the triptych to the 1400’s. The pulpit was made in 1707 by Joakim Lutkenschwanger.
The cemetery is surrounded on three sides by a churchyard wall of granite from the 1200s. On a hill northwest of the church is a bell tower which was built in 1739 by Rafael Puset.References:
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.
