Can you believe it, the rev actually squeezed in past those wiggly stones at the front and set about diligently measuring the stones inside? What a star.
This remain is one of the most considerable in the island measuring one hundred and thirty four paces in circumference. On walking round it we observed a square opening on the south side which I entered on my hands and knees and found it about ten feet long, four wide and three high, the sides formed of three large flat stones placed edgeways in the ground supporting the roof which consists of only two.
