Llandaff Cathedral underwent extensive restoration between 1843 and 1869 under the direction of John Prichard, whose work defined the neo-Gothic aesthetic across south Wales. A product of the Prichard family of Collenna, he spent his professional career operating from Llandaff as the appointed diocesan architect, shaping the regional ecclesiastical landscape through numerous building and renovation projects.
Professional Formation and Influence
Born in Llangan on 6 May 1817, Prichard was the twelfth son of Richard Prichard, the vicar-choral of Llandaff. He received his formal architectural training under the tutelage of Thomas Larkins Walker. This apprenticeship exposed him to the theories of Augustus Pugin, which underpinned his preference for the neo-Gothic style throughout his career. In December 1844, he formally established his practice in Llandaff, assuming the role of Resident Diocesan Architect.

Between 1852 and 1863, Prichard worked in partnership with John Pollard Seddon. Their most significant collaborative effort involved the long-term restoration of Llandaff Cathedral, a project that spanned decades. The south-western tower of the structure was completed in 1869 based on Prichard's individual design. While a significant portion of their combined work in the region suffered destruction from aerial bombardment during the Second World War, records highlight their involvement in projects such as the Old Probate Registry and the Church of St John in Llandenny.
Ecclesiastical and Secular Projects
Prichard's portfolio included diverse commissions beyond church restoration. He designed Nazareth House in Cardiff, a Catholic almshouse facilitated by land granted by John Crichton-Stuart, 3rd Marquess of Bute. He also undertook secular work, including the restoration of Ettington Park, where his brother Richard served as vicar, and the construction of the Grade II listed Prichard Bridge in Llandaff around 1880. This structure originally facilitated carriage access to the local corn mill.
Final Years
Prichard remained active in his profession until the end of his life. He oversaw the construction of St Mary’s Church in Whitchurch, Cardiff, in 1884. He died unmarried and childless on 13 October 1886 at the age of 69. Following his death, he was interred on the south side of Llandaff Cathedral, and his professional responsibilities as diocesan architect were assumed by his former partner, John Pollard Seddon.
