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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
