Sunday School

The Sunday School, dated 1882 (as shown on a rainwater head), is constructed of Ruabon red brick with red machine tile roofs, some of which are hipped, and features ornamental ceramic cresting and finials. It is built in a Vernacular Revival style. The building comprises a wide 'nave' to the right, a hip-roofed 'transept' set to the left, and a lower range attached to the left gable end of the nave. It is one storey high with an attic.

The fenestration is scattered throughout, using multi-paned leaded windows. The 'nave' has a gabled dormer breaking the eaves to the left, featuring carved brackets supporting bargeboards. A similar dormer to the right incorporates stepped lights with transoms and cinquefoil heads, as well as blind quatrefoils to the woodwork above a four-light mullion window. A hip-roofed projection has two three-light mullion windows to the ground floor, each with a segmental-headed relieving arch above. The first floor of this projection features two two-light Gothic-style windows with a moulded cill set in a pointed relieving arch, with green-glazed ceramic ornamental infill depicting cherubs in the window heads. A large, oval-shaped medallion, also with green-glazed panels, depicts Christ in Glory, seated with a child, and includes the inscription "SUFFER LITTLE CHILDREN TO COME UNTO ME" and, below, "OF SUCH IS THE KINGDOM OF HEAVEN." Bracketed purlin ends and collar are present on the overhanging gable, which has a diamond-shaped integral end stack.

The circular turret to the front right-hand corner has a hip-roofed design and narrow rectangular slit openings (providing lighting for an internal staircase) at different levels, displaying blind cusped heads. It also has a stepped Lombard frieze below a viewing gallery, incorporating small fixed-light windows. The conical spire of the turret is angled and topped with an elaborately decorated cast-iron finial. A seven-panel door is located to the left side of the turret on the ground floor. A lower, hip-roofed range attached to the left gable end of the 'nave' has a five-light mullion window to the front, and a small louvre to the left, capped with oak shingles in a pyramidal shape. The rear (west) elevation is of similar style, with a porch to the left and a hip-roofed projection mirroring its front counterpart.

Inside, the 'nave' is characterized by an elaborately trussed roof with curved braces and iron ties, as well as an iron grille to the gallery at the 'west' end, with built-in bookcases in the room below. Walls are finished with exposed yellow brick and brown-glazed tiles, and a pointed stone arch with leaf moulding defines the 'east' end. A pointed recess behind this arch displays floral and leaf decoration to the tiles, alongside the inscription "TAKE FAST HOLD OF / INSTRUCTION / LET HER NOT GO / KEEP TO HER / FOR SHE IS THY LIFE;" A stained glass window is located on the right. Ornate tile fireplaces are found in the 'nave' and the lower range, the former featuring fleur-de-lys decoration. The turret contains a stone spiral staircase with cast-iron stick balusters leading to the top. The Sunday School cost £4000 to construct.
