Church of All Saints, Pen-y-Fai

The interior was designed and fitted according to Llewellyn's whims and is a curious combination of Danish and Roman influences. The polychrome effect was achieved from a variety of quarries and manufacturers: the walls are ashlar, in local grey-green Quarella stone, with bands of Ham stone from Somerset. The nave has a mosaic floor composed largely of green tessserae and made by the Vitreous Mosaic Co of London. The chancel has steps of white Great Belton and black Ashburton marbles from Devon.

The nave has an arched-brace roof with wind braces and with a frieze of arcading above the wall plate. The E and W crossing arches have moulded capitals above short shafts with head corbels of archdeacons, below which are the emblems of the Evangelists. Inside the crossing are 4 brackets at high level carrying sculptures of the 4 bishops of Wales. The chancel has a boarded wagon roof with cherubs at the feet of the ribs. The E window has a rere-arch with detached Purbeck shafts with shaft rings. The piscina and sedilia have detached Purbeck shafts (in white marble to the piscina) and cusped arches in Early English style; in the N wall is a Bishop's seat in a niche, inside which is a Madonna in bas-relief made of Roman Terracotta and brought from Florence. The reredos is by William Clarke of Llandaff and of pink Penarth alabaster, the niches of which have gold mosaic backgrounds. Shafts between the niches are of green Conomara marble. A central group of 3 niches has figures in Castelina marble by Goscombe John (the Nativity, Crucifixion and Descent), either side of which are three apostles in Derbyshire alabaster. The E window by James Powell & Sons has glass depicting the risen Christ flanked by Saints Leonard and David. In the nave windows are shields bearing the arms of Eton and Winchester schools, the 4 dioceses of Wales and of Canterbury and Gloucester. The pulpit, by Llewellyn and Clarke, is circular, of Quarella stone but with five figures (Peter, John the Evangelist, Christ, Matthew and Paul) in china and made at the Royal Danish Porcelain Factory in Copenhagen, and with a cornice of Penarth alabaster. It also has shafts of red Ogwell marble and a pedestal of Penarth alabaster. The font is a copy of Thorwaldsen's Angel Baptism in Copenhagen, comprising a life-size sculpture of an angel of Carrara marble on a slate-coloured marble base. The window immediately adjacent to the font has glass depicting John the Baptist. Oak choir stalls were made by Clarke of Llandaff; the nave has plain benches. A lacquered brass communion rail is by Benham & Froud of London.
