Hall attached to Calfaria Chapel

The hall, dated 1871, was added to Calfaria Chapel. It presents a three-bay classical front with a pediment, interrupted by a centrally advanced full-height bay. The construction is of coursed rubble with freestone dressings, including a moulded cornice, quoins and plinth, and is roofed with slate, featuring some cresting and boarded eaves. A stone roundel sits at the top, featuring a bricked-up quatrefoil above a datestone with swags. A larger wheel window is centrally positioned, with a swept freestone surround. The main entrance below has a deeply moulded round arched surround and panelled doors with an intersecting Gothic fanlight, leading to semi-circular steps. The outer bays feature horned small-pane sash windows with marginal glazing bars. Cornices and blind panelled aprons are present at the gallery level, and voussoirs detail the ground floor. The façade continues around the corners. The side elevations are four-bay, with a high plinth serving as a ground floor sill, matching sash windows, and round arches above square heads.

A further hall section, also dated 1871, is set transversely and projects to either side at the far end; its construction is of snecked rubble with a slate roof. The front facing Griffith Street presents a three-bay gabled design, with tall round arched windows featuring glazing bars and Y-shaped heads. A central panelled door with an intersecting tracery fanlight is also present. The rear is finished in cement render with horned twelve-pane sashes.

The burial ground contains several good later 19th-century monuments, including one dedicated to the notable Dr Thomas Price. It is bordered by a rubble wall to Monk Street and slopes up Griffith Street with rounded coping. There are two entrances: the main one is in Monk Street, featuring gate piers capped by glass lamps on metal bases (one is missing), while the Griffith Street entrance is opposite the Bethania Ysgoldy.

The rectangular interior features a coved and boarded ceiling, with roses at the corners and centre and a diamond-shaped panel with plaster foliage detail. A raked gallery projects significantly into the space, supported by cast iron columns with a bowed cast iron front featuring intricate foliage. The platform and steps leading to the “set fawr” are further accentuated with cast iron newels with gilding and ball finials, and barley twist balusters. A baptistery is located beneath. The organ case is of simple Gothic design. A hall to the rear boasts a five-bay roof with a boarded ceiling and billet moulded cornice. A gallery occupies one end, featuring a panelled timber front swept round at the ends.
