St. Maria Lyskirchen is the smallest of the twelve Romanesque churches in Cologne. It was founded in 948, and the present building dates from 1210-1220, with some later additions in the Gothic style. The upper parts of the west front were rebuilt in the 19th century. The church is in the form of a three-aisled basilica, with a chancel flanked by two towers, only one of which was constructed to its full height, and an eastern apse. The building received only minor damage during the wars.
The church has a sculptured Romanesque portal, and a cycle of 13th century ceiling paintings. Rediscovered in the 19th century, they are unique in Cologne and show stories from the Old and New Testaments. The church contains the 'Schiffermadonna' (Seaman's Madonna), a wooden statue of 1420. A triptych by Joos van Cleve, with a central panel of the Lamentation, was sold in 1812; a few years later it was replaced with a copy by Benedikt Beckenkamp, which remains in the church.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.
