The small church of Oratorio di Santa Maria in Valle (also known as Lombard Temple), next to the Natisone river, is a notable example of High Middle Ages art sometimes attributed to the 8th century, but probably later. Included in the old Lombard quarter, it was probably used as Palatine Chapel by the Lombard dukes and king's functionaries. The fine decorations, statues and stuccoes (11th or 12th century) housed in the interior, show a strong Byzantine influence.
Cividale del Friuli, the capital of the first Lombard duchy in Italy has been present in the UNESCO World Heritage Site list since 2011.Cividale del Friuli, thanks to the Lombard Temple, one of the most representative symbols of the Lombard power in Italy, has received this important award being included, together with other Italian cities that preserve prestigious Lombard evidence.
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.
