Llandovery Castle is a late thirteenth-century ruin which occupies a knoll overlooking the River Towy and the land surrounding it. The Normans built a castle in the current location in the early twelfth century and this was rebuilt in stone. It was burnt in the early sixteenth century and never repaired.
A Norman knight, Richard Fitz Pons, received the lordship of Cantref Bychan in 1116 and he probably began construction of a motte-and-bailey castle in same year. It was repeatedly lost to the Princes of Deheubarth over the next several generations. King Henry II of England spent a great deal of money repairing the castle in 1159–62, but the Welsh captured it regardless. It finally fell to the English under Edward I in 1277. It was briefly retaken by Welsh forces under Llywelyn ap Gruffudd five years later. The castle was then granted to John Giffard, 1st Baron Giffard, who likely rebuilt it in stone. The building passed to the baronial Audley family of Heleigh in 1299 (who later inherited the lordship of Cemaes in north Pembrokeshire) and then into the Touchet family in the fourteenth century. King Henry IV of England visited the castle in 1400 and it was besieged during the Owain Glyndŵr rebellion three years later. The castle was burnt in a rebellion led by Hywel ap Rhys in 1532 and was never rebuilt.
The keep is a large D-shaped tower on the western side of the castle. The gatehouse has two towers on the north side with a well-tower. There are also remnants of the curtain wall around the filled-in ditch.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
