Exterior St Helen's is constructed in the
Perpendicular style of rubble with
ashlar dressings. Its plan consists of a
clerestoried nave with
aisles to the north and south, a chapel and porch to the south, a tower to the west, and a
chancel, which has north and south aisles and a north
vestry. The roofs are low-pitched. The chapel and aisles have a plain ashlar
parapet. The west tower has six stages. It has angled
buttresses on the west side and a
crenellated parapet. There is a
turret on its north-east corner, which has a
spire. The
belfry louvres have
trefoiled two-light openings with square heads. There is also a small, square window at the level of the bell-ringing chamber. The north wall of the tower has a clock.
Interior and fittings Internally, the tower measures square. It is entered from the nave through an arch of two hollow
chamfered
orders. The nave measures by . It is separated from the north and south aisles by five-
bay arcades, with pointed arches and round
piers. There is a recumbent
effigy in the nave to Alexander Butler (d. 1726). The
Lady chapel south of the south aisle, endowed by Lady Rigmayden of Wedacre in 1529, is accessed through two pointed arches. It was founded by Margaret Rigmaiden (d. 1516) of Wedacre. The chapel contains a
piscina (basin), which has a cusped head. On the wall there is an inscription in Latin warning of "idle chatter in church". The chancel measures by . The pointed chancel arch separating the chancel from the nave is in the
Decorated style; it has two orders with wave
moulding. The vestry at the north-east corner of the building is mostly constructed of
dressed stone, which contrasts with the rubble of the rest of the church. The
stained glass in the church dates mostly from the 19th century. It includes work by
Ward and Hughes,
William Wailes and
Heaton, Butler and Bayne. The tower houses a
ring of six bells hung in a wooden frame, that are rung from the ground floor. They were cast in 1828 by Thomas Mears at the
Whitechapel Bell Foundry in London. ==Churchyard==
