Sammallahdenmäki is a Bronze age burial site including 36 granite burial cairns dating back more than 3000 years, from 1500 to 500 BC. Sammallahdenmäki is an exceptionally valuable example of Finland’s Bronze Age culture because it presents the ancient monuments in a well-preserved natural milieu. It’s designated as the UNESCO World Heritage Site in 1999.
Two of the most spectacular cairns are the quadrangular "Chuch Floor" and the dike-like "Long Ruin of Huilu". A typical feature of the Sammallahdenmäki cairns are the stone cists, boxlike structures formed by stone flags standing on edge and forming end and side walls or only one or the other. The cist may have originally contained a body in a wooden coffin, or the dead person may have been wrapped in animal skins. On the other hand, the cist may also have served as a receptacle for the ashes of a cremation burial. Remains of cists are still visible in some of the unexcavated cairns as well as in one cairn reconstructed after investigations.
Direction signs guide the visitor to Sammallahdenmäki from Highway 12 (Rauma–Huittinen). At the township of Lappi, the route turns north along Road 2070. After ca. 3.5 km the route turns left along a side road marked by a direction sign. The route ends at an information sign.
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.
