Throop United Reformed Church and Sunday School

Throop United Reformed Church and Sunday School, built in 1819 and originally a Congregational church, features a stucco front in the Regency Gothic style. It has three windows with Y-tracery above a Victorian lean-to narthex that includes a gabled doorway. There is a single-storey annexe with a doorway and another Y-tracery window. The sides of the building have two tiers of uniform Y-tracery windows made of whitewashed brick, with Y-timber bars and horizontal iron bars.

Attached at the rear and at right angles is the Sunday School, built in 1830 and rebuilt and enlarged in 1860, constructed in red brick with an Italian-medieval style. It has a pedimental gable with a notched brick outline, walls featuring vitrified headers, and flank windows that are round-arched and arranged in pairs, separated by pilaster strips. The annexe at right angles includes a round-arched pair of windows and a 'porthole' window in the gable.

The interior of the chapel remains unspoilt, with pale blue walls, deeply splayed windows, a thin cornice, and deep coving on the ceiling outlined by roll-moulding. The west gallery features a panelled front with pilasters and a coved cornice supported by two chamfered columns. The east wall has a tripartite panel with an arched centre, likely originally intended for the Creed and Commandments. The pews are Victorian and made of pitchpine.
