Why this matters
Llandaff Cathedral was founded in the 7th century and dedicated to St Dwynwen, later rededicated to St Chad. It was rebuilt in the 12th century and became a significant religious and cultural center in medieval Wales.
Overview
Llandaff Cathedral grew from a church founded in 1107 into the seat of the Bishop of Llandaff. Rebellion, soldiers, storms and a wartime mine repeatedly wrecked its fabric, yet medieval stone, Victorian repair and the bold post-war rebuilding now stand together as evidence of nine centuries of worship and recovery.
Foundation and growth
The cathedral's recorded foundation dates to 1107, with a major rebuilding between 1120 and 1133. A chapter house, Lady Chapel, north-west tower and a renewed main church were added during several later campaigns extending across roughly four centuries.
People and events
The church is dedicated to Peter and Paul and to the Welsh saints Dyfrig, Teilo and Euddogwy. John Wood the Elder began an unfinished replacement in 1734; John Prichard led Victorian restoration, and Jacob Epstein created the post-war Christ in Glory.
Damage, loss and survival
Owain Glyndwr's rising and Parliamentarian occupation both brought destruction. The storm of 1703 helped push the neglected roof towards collapse in 1723, while a parachute mine tore open the nave and nearby parts during the Cardiff Blitz. Post-war rebuilding finished in 1960.
Why it mattered
As the diocese's mother church, Llandaff links early Welsh saints, medieval bishops and modern Cardiff. Its mixed Romanesque, Gothic, Victorian and post-war work makes repeated destruction visible rather than reducing the building to a single age.
