The Ffynogion Earthwork
A curiosity. In Llanfair D.C. parish, a couple of miles south of Ruthin is an enclosure which has been interpreted variously over the years since its discovery. A large earthwork, over 130 metres in length and 56 metres in width, rectangular with three connected ditched and banked enclosures. Initially, it was thought to be a motte and bailey castle, although this has now been generally debunked, and it is more than likely the earthen remains of a formal garden, worked into a still marshy water meadow. It remains entirely a mystery, since no documentation has ever been found to explain it. There is even a lack of legend surrounding the site.
