Newport Cathedral, also known as St Woolos Cathedral, is the seat of the Bishop of Monmouth. The name 'Woolos' is an English corruption of Gwynllyw, the 5th-century Welsh saint who first founded a religious establishment on the site.
An early wooden church is known to have stood on the site from sometime during the Welsh Age of the Saints. This was rebuilt in stone in the 9th century indicating the importance of the cult of Saint Gwynllyw and the wealth of the shrine, as stone buildings from this period are very rare. Sections of the present building date from Early Medieval times and part of this stone building is now incorporated into the present building as the Galilee chapel located at the western end of the cathedral. A pirate attack circa 1050 left the structure in ruins.
In about 1080 the Normans built a new nave to the east of the Saxon ruins, and a lean-to south aisle, building a new entrance archway through the Saxon wall. Circa 1200 the Saxon church was repaired so the Norman entrance became an internal archway.
It was badly damaged in 1402 when Newport was attacked by the forces of Owain Glyndŵr and underwent a major rebuilding including the addition of the tower.
It also seems to have been damaged in the English Civil War period when a statue above the main entrance representing a benefactor of the church seems to have lost its head. It is either Jasper Tudor, the Earl of Pembroke, or Humphrey Stafford, 1st Duke of Buckingham as both helped rebuild it after Glyndwr's attack.
The cathedral has been partially rebuilt or extended in every period up to the 1960s.
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).
