Saint Jacques-sur-Coudenberg is a neoclassical church located in the historic square of Place Royale in central Brussels. The medieval abbey church that originally stood on this location was demolished by command of Charles Alexander of Lorraine during his expansive urban planning projects, despite having escaped the great fire of 1731 that destroyed the nearby Coudenberg Palace. The new church was built in line with rue Montagne de la Cour/Hofberg on its present location at the Place Royale. Construction of the facade was started by architect Gilles-Barnabé Guimard after the designs of Jean-Benoît-Vincent Barré (1775). The first stone was solemnly laid by Charles Alexander of Lorraine on the 12th of February 1776. The portico was finished in 1780. The nave, transept, choir and sacristy were built under supervision of Louis Montoyer in the years 1785-1786. After the consecration of the building it was in use as abbey- and parishchurch at the same time. Moreover it was the official church of the court of the Governors of the Habsburg Netherlands. The present building was designed to serve as the Church of the Abbey of Saint-Jacques on the Coudenberg and therefore has a deep extended choir with place for choir stalls for the monks.
During the French Revolution, the abbey was suspended and the church was made into a Temple of Reason, and then later into a Temple of Law. The church was returned to Catholic control in 1802. On July 21, 1831, Prince Leopold of Saxe-Coburg-Gotha took the oath that made him H.M. Leopold I, the first King of the Belgians, on the front steps of the church. The building lost somewhat of its typical neoclassical temple-like appearance by the addition in the 19th-century of a bell tower (after the design of Tilman-François Suys) and a coloured fresco by Jean Portaels on the pediment.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.
