Oseberghaugen is a Viking era burial mound. The Oseberg ship was found in the Oseberg burial mound in 1904. This Viking longship is now in the Viking Ship Museum in Oslo. Archaeological excavations in 1904 uncovered history's largest and richest example of craftmanship from the Viking Age. In addition to the Oseberg ship, Oseberghaugen contained the Oseberg carriage, five beautifully carved bed-posts shaped like animal heads, four sledges, beds, chests, weaving-frames, household utensils and much more. Scientific examinations in 1992 now date the burial to 834 AD, and indicate a probability that it was Queen Alvhild, the first wife ofKing Gudrød, who was buried here.
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.
