Goward Dolmen is a megalithic dolmen or cromlech situated between Hilltown and Castlewellan The huge granite capstone has slipped from its original horizontal position. The capstone is 4m long and 3m wide, with an estimated weight of 50 tons. The capstone has shifted sideways on its supporting uprights, possibly due to the collapse of the backstone, and now overhangs the chamber on its north side. The unsegmented burial chamber is 9 feet long with an entrance on the east, flanked by orthostats which could be the remains of a crescent shaped facade. Its largest stone is the enormous capstone which has fallen sideways, revealing the megalithic chamber it once covered, in which a cremation urn and a flint arrowhead were found in 1834. Stones standing independently at the eastern side of the monument suggest that it may once have had a forecourt facade like a court-tomb.
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.
