The Turkansaari Open-Air Museum consists over 40 museum buildings. The buildings include for example a church built in 1694 and the old country manor house of Ylikärppä, completed in 1894. In Turkansaari, you can see the old trades that the region’s economy used to revolve around, including tar-making, salmon fishing, lumbering and log floating.
Turkansaari church was built as the chapel in 1694. At that time Turkka Island was a bustling marketplace for Oulu River. The island, however, lost its position as a marketplace and the market ran out of grip in the 1700s. Been abandoned for a long time the church was demolished and sold to be used as the fishermen warehouse in 1814.
Local inhabitant Östen Elfving bought the church in the early 1920s. The church was moved back to its original position in Turkka Island in 1922. Because the original interior was not preserved, Turkansaari church was restored using parts from the other equivalent small churches built in the 17th century. The front door is from the Enontekiö Markkina church. The pulpit is a model copied from the old church of Sodankylä.
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.
