Capel Saron including vestry, forecourt railings and gates

Capel Saron is a chapel built in 1843, featuring unpainted render with some stucco details and a slate roof with bracketed verges on its broad gable front. The façade includes two central arched windows and two outer arched doors, along with a large lunette plaque in the gable that reads 'Methodistiaid Calfinaidd 1843 Saron' in later 19th-century lettering. The windows are large, 20-pane designs with intersecting glazing bars in the heads, and the fanlights of the doors match. All windows and doors have moulded stucco arched hoods; the hoods over the windows are linked to an impost band, while those over the doors rest on small console brackets. The doors are plain and flush.

The ground slopes down at the rear, where there is a basement vestry. The northern side wall is made of rubble stone and features three later 19th-century yellow brick arched windows, with a basement door to the right and an added outbuilding to the left. The rendered plain rear wall has two arched windows and a louvred gable opening. The southern side wall is also rendered and has three similar arched windows, with a basement sash window to the left.

A late 19th-century vestry extends forward to the right, featuring a two-window range in its end gable facing the street and a red brick end stack. The attached forecourt has low roughcast walls with slate coping and low iron railings, along with two plain gatepiers and double iron gates. The gates are adorned with cast iron spearhead rails and urn-capped stanchions, and they include matching dog-bars.

Inside, the chapel has a plain large interior with numbered pitch pine pews arranged in three blocks that are slightly raked towards the rear. The pews have shaped bench ends, and the front pew features two ornate scrolled rails dividing it. The set fawr, located between the entrance lobbies, has turned balustrades over panelling, which terminate at heavy turned newels topped with ball finials. The angles are curved. The platform has similar newels at the steps on each side and at the front of the pulpit. The pulpit itself has a panel front between piers, with heavy brackets supporting a bookrest; the upper horizontal panel features three roundels. All panels have chamfered and stopped surrounds. The ceiling is plain, with a cornice and three small roses. The vestry beneath the chapel at the rear is supported by plain iron pillars.
