Interior
Seven-bay nave with arch-braced roof, the braces supported on scalloped corbels. Pointed chamfered chancel arch of 2 orders, the inner order supported on pendant corbels. The chancel is of 3.5 bays, with high arch-braces supported on hollow decorated corbels, with low arcading rising from the wall plate. The roof members, underside and wall plate are painted and gilded. The chancel walls are fully lined in marble, grey with red bands and a decorated coloured frieze to the tops of the side walls. The floor is also of decorated marble, in red, white and black. Surrounding the sanctuary is an ornate red marble reredos with blind arcading. The trefoil-headed arches are supported on black columns. Behind the altar, the reredos is 2-tier and flanked by pilasters. The upper tier has blind trefoiled arches under gables, flanking a wide trefoil-headed ogee arch on black columns, immediately behind the altar. It is surmounted by a cross and has foliate decoration in the spandrels.
A pointed arched doorway leads N to the vestry, with planked door under a recessed trefoiled tympanum. To its L is the organ of 1962. Gilded altar rail with barley twist uprights supporting large scrolls. Two rows of choir stalls with panelled fronts surmounted by friezes of crosses in open circles. Wood panelled polygonal pulpit to L front of nave with narrow open lancets and foliate motifs. The pews are in a similar style with angular bench ends with ogee decoration. Painted octagonal font at W end tapering down to a circular stem on a low plinth. Small incised crosses in circles to the quadrant faces. Two church bells dated 1999 by Taylor, Loughborough, lie next to the font.
The E window has stained glass depicting the Ascension, donated by the Elba Steelworks Company, c1885. The chancel S windows also contain stained glass; the single-light sanctuary window depicts St John the Divine writing the last book of the bible, and is probably contemporary with the lining of the chancel with marble, c1900. The 3-light window to the R depicts the Transfiguration of Christ in the centre; the Last Supper to the L and the call of James and John to the R light. Attached to the raked sill below are 3 marble memorial tablets, to John Dillwyn Llewelyn (d 1882); Jessie Eliza, wife of Colonel J R Wright, who was a benefactor and 1st organist at the church (d 1896); and to William Greener, 1st choirmaster (d 1895).
Two of the S nave windows contain stained glass. The single light E window of 1953 is in memory of steel maker Sir William Charles Wright, 1876-1950, and was dedicated by his sister. The stained glass is by Lawrence Lee (who also designed windows at Coventry Cathedral). It depicts Jesus, the Good Samaritan, offering a cup of nourishment to a man in need. In the background are blast furnaces, whilst 3 roundels at the bottom show steel-making scenes; furnaces, a rolling mill and a bar mill. A marble tablet to Jessie Ethel, the sister of William Wright (d 1955), was placed on the sill beneath the window. The 2-light window to the R bears a depiction of Peter with John healing the lame man at the gate of the temple. It is dedicated to Sir John Roper Wright (d 1926) and his wife Jessie Eliza (d 1896). The remaining windows have pink and green quarries.
The N wall bears 2 war memorials. Ornate WWI memorial to L consisting of cream marble surround with pilasters, plinth and flat head. Inside is an ornate trefoil-headed arch surmounted by a large cross, under which is a list of the men who died. Plainer grey marble tablet on black background to R, the cornice reading '1939. Our Glorious Dead. 1945'.
