Mechelen town hall on the Grote Markt consists of two parts: the cloth hall with unfinished belfry and the Palace of the Great Council. The cloth trade went into decline in the 14th century and there wasn't the money to complete the building. For two hundred years the belfry was no more than a shell, until it was eventually provided with a temporary roof in the 16th century. The belfry is now a UNESCO world heritage site. On the right of the belfry you can see the oldest part of the town hall, the remains of the earlier cloth hall. On the left is the Palace of the Great Council. The Great Council never actually met here, because this wing was only completed in the twentieth century in accordance with the original sixteenth-century plans of the then leading architect Rombout Keldermans. The interior of the Town Hall is well worth seeing.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.
