Arthur's Stone (Maen Ceti in Welsh) is a Neolithic burial tomb on the north of Cefn Bryn on the Gower Peninsular, Wales. The suggested date of the tomb is some 2500 years BC.The name comes from any one of a number of tales and legends that link King Arthur to the area. At 4m long, 2m wide and 2.5m tall, the capstone stands on a series of supporting stones around the base to leave a hollow tomb beneath. The stone weighing in at 25 tonnes was originally left during the last ice age. However, the stone is some 10 tonnes lighter than when first mounted as sometime prior to 1693 the rock split in two. The exact reason is not known, but as with the name, many tales and legends abound as to the cause. King Henry VII and his troops, upon landing at Milford Haven whilst on their way to the battle of Bosworth Field in 1485 are said to have made a detour to visit the famous stone. It was first excavated in 1870 by Sir Gardiner Wilkinson. To the west 105m away is Great Cairn, a circular pile of stones 16m diameter above a central grave.
