The Cremona Baptistery is annexed to the city's Cathedral. Built in 1167, it is characterized by an octagonal plan, a reference to the cult of St. Ambrose of Milan, symbolizing the Eight Day of Resurrection and, thenceforth, the Baptism. The edifice mixes Romanesque and Lombard-Gothic styles, the latter evident in the preference for bare brickwork walls. To the 16th century restorations belong the marble cover of some walls, the pavement and the baptismal font (1531) and the narthex (1588) of the entrance, in Romanesque style, work by Angelo Nani.
The interior has a 14th-century Crucifix, over the St. John altar, and two wooden statues portraying 'St. Philip Neri' and 'St. John the Baptist' by Giovanni Bertesi. Over the ceiling is a 12th-century statue of the Archangel Gabriel.
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.
