Anthropology professor. The image is of a wall surrounding Ysbyty Cynfyn, an early Christianised site and graveyard in Wales, UK. It is evidence that Christianity took over and desecrated ancient sacred sites. The large monolithic standing stone incorporated into the wall, is the largest of five remaining, once sited on a raised platform that formed a henge sacred circle. The missing stones were used by the Church as building material. The Church and oldest burials are within the raised circular platform. http://www.megalithic.co.uk/article.php?sid=1375
