Exterior Apart from the slate roof, all the visible fabric of the church is terracotta, the use of which allowed for a high degree of decoration. The plan of the church is
cruciform, conmprising a
nave with a west porch (the original base of the tower), two wide
transepts, a short
chancel, and a
vestry in the angle between the north transept and the chancel. Externally, the nave is divided into five
bays by
buttresses surmounted by
finials. Each bay contains a two-light window in the
Decorated style. The transepts and chancel are similarly divided, with four-light Decorated windows at their ends. An openwork
parapet runs along the top.
Interior Internally, the timber
hammerbeam roof is carried on terracotta
corbels. The interior is richly decorated with
friezes, ball-flowers, foliage, inscriptions, panels, and
blind arcades, all executed in terracotta. Behind the altar, forming a
reredos, are
niches and panelling incorporating the words of the
Ten Commandments, the
Creed, and the
Lord's Prayer. Terracotta also forms the pew ends, which are decorated with
poppy heads, as well as the organ case. The original altar, together with the octagonal
diapered font and
pulpit, were likewise made of terracotta. The stained glass in the east window, and in several other windows throughout the church, is by
Thomas Willement; one of these depicts the execution of
Charles I. A window in the south transept, by
William Wailes, illustrates the
stoning of
Saint Stephen, while a window in the north transept was designed by
Henry Holiday in 1884. ==Context and assessment==
