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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
