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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
