The Trust Deed states that the Chapel is a place of Christian worship to be "frequented and enjoyed by a congregation of Protestant Dissenters of the Calvinistic persuasion professing ..".

[3] Huntington, originally from Cranbrook in Kent, was an orthodox but controversial Calvinist preacher who ministered at Providence Chapel, Grays Inn Lane, London.

Known by various pseudonyms, he became very popular in southeast England in the early 19th century, and helped to found several Calvinist chapels.

[4] A Sunday school was built in the grounds in 1874; it was linked to the chapel's north wall by a columned porch surmounted by a pediment.

[8] The chapel's use declined in the 20th century,[7] and the Loyal Orange Institution of England, Southdowns Lodge used it for their annual commemorative service on the Sunday prior to November 5.

[11] It quickly became established across Northern Ireland, where dozens of churches were founded, and some congregations developed in the rest of Great Britain as well.

[3][8] The entrance is at the east end and is framed by a porch with columns of the Tuscan order, described by Nikolaus Pevsner as "over-broad".

The roof is covered with slate tiles and has a small boxlike louvred projection, topped with a pyramid-style cap, in the middle.

[8] Inside, wood predominates: the barrel-vaulted timber roof is supported on wooden columns attached to the gallery which runs around all four sides of the interior.
