The Basilica of the Holy Apostles (Basilika St. Aposteln) is one of the twelve Romanesque churches built in Cologne in that period. Its glory is the domed clover leaf chancel, which was built around 1200. The story of how today’s building originated begins in the 11th century.
At that time the church was on the road in the direction of Aachen, directly ahead of the roman city walls at the western main gate.
In the 13th century the church was significantly enlarged. In addition to the clover leaf chancel there was also the octagonal dome above the crossing, which was added at this time, which gives St. Aposteln its monumental, almost Byzantine appearance. The old structures were retained and, in spite of the building modifications, were copied and integrated into the new construction project.
The sequential and complementary building phases can be well identified in the St. Aposteln church. An extraordinary and controversial combination of historical and modern art is shown with a glance into the choral arches: the modern paintings by Herrmann Gottfried from the years 1988 until 1994 always provoke a host of diverse opinions.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
