The Gannarve grave is outlined by large standing stones, forming the shape of a ship. It has been built at the end of the Bronze Age, about 1100 – 500 B.C. The grave is 29 metres long and 5 metres wide. It is only one of about 350 boat-shaped graves on the island. In most cases, only one burial has been uncovered in each grave. When these people were buried, it was a custom to cremate the dead on a pyre. After cremation, the bones were crushed and washed before they were placed in an urn.
There were once two boat-shaped graves here at Gannarve. One of them fell victim to the plough long ago. The existing grave was almost destroyed in the same way. Only the stem stones remained when archaeologists started excavating the monument in 1959. The excavation uncovered soil marks of all the removed stones beneath the peat. Consequently, the reconstruction of the entire grave was not too difficult.
There were plenty of large stones lying right next to the grave, and it is quite possible that several of the stones used once actually belonged to the original grave.
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.
