Archaeologia Cambrensis 1887 Page 349. Proceeding from the Castle a distance of about 300 yards, to the south, Twt Hill [Map], the site of the earlier castle built by Llywelyn ap Sitsyllt, King of Gwynedd c. 1015, was passed; and a little further on are the remains of the Dominican Priory [Map], now called the Abbey. Here, again, under the same guidance, were seen the windows of the monks' dormitory, above the present barn; and built up into the Avails, a large monumental slab with an incised effigy of an Archbishop of Rages, a former brother of the house. Near it was a cross ragule, memorial to "De Bridelton' cuius a'ie p'piciet." Other floriated crosses lie near the front door of the farmhouse, whilst in the garden wall are portions of window-tracery. There is a much damaged effigy of a knight in the wall of the stable; and behind the buildings on the opposite side of the yard (the western) may be seen several Pointed windows that show that portion to have been a part of the old monastic building. The property now belongs to Sir W. G. Williams, Bart [aged 42]., of Bodelwyddan, and it is much to be desired that these interesting relics should be more carefully protected. The lateness of the hour and the shades of evening rendered it too dark to see the church, and it had reluctantly to be omitted for the day.

Chronicle of Abbot Ralph of Coggeshall
The Chronicle of Abbot Ralph of Coggeshall (Chronicon Anglicanum) is an indispensable medieval history that brings to life centuries of English and European affairs through the eyes of a learned Cistercian monk. Ralph of Coggeshall, abbot of the Abbey of Coggeshall in Essex in the early 13th century, continued and expanded his community’s chronicle, documenting events from the Norman Conquest of 1066 into the tumultuous reign of King Henry III. Blending eyewitness testimony, careful compilation, and the monastic commitment to record-keeping, this chronicle offers a rare narrative of political intrigue, royal power struggles, and social upheaval in England and beyond. Ralph’s work captures the reigns of pivotal figures such as Richard I and King John, providing invaluable insights into their characters, decisions, and the forces that shaped medieval rule. More than a simple annal, Chronicon Anglicanum conveys the texture of medieval life and governance, making it a rich source for scholars and readers fascinated by English history, monastic authorship, and the shaping of the medieval world.
