Moel Tŷ Uchaf Moel Tŷ Uchaf is a monument near Corwen, Wales, and could date to about 1800 bc. The circle is 12 metres in diameter, and Moel Tŷ Uchaf is also the name of the hill on which the circle is located. Of the 41 stones on the circumference, one further stone is at stone 'ten' anti-clockwise (inside), and one stone is at 'eleven' clockwise (outside), making 43 in total. The outside stone makes an angle of 19° with the centre and the inside stone an angle of 50°. The stones can be considered as split 34/7 or 41/7, the latter is considered as the seven is separate but not minus making it a part of it, this then gives the number 5.857. This number produces a possible date along with the width from a 45 ft width. 41÷7=5.857 5.857÷1.55=3.778 3.778×1000=3778 3778-1985=1793 bc Width 1200÷30.48=39.37 39.37-45=5.6299 5.6299÷1.55=3.632 3.632×1000=3632 3632-1985=1647 bc Stones Using the angle of 6° (5.857°) clockwise, the following are produced
