Saron Congregational Chapel, including attached schoolroom

The building comprises Saron Congregational Chapel and an attached schoolroom. The chapel was built in 1858, although a previous chapel existed on the site from 1819 and was rebuilt in 1828. The chapel has a stuccoed classical facade with a slate roof. The front is three bays wide and features a pediment supported by giant Ionic pilasters. The entablature is slightly recessed in the central bay, with a stuccoed arch rising into the pediment and bearing the inscription "Saron Independent Chapel". Tall, round-arched windows have simple glazing, moulded architraves, and vermiculated keystones. A blocky stringcourse runs at sill level, with rusticated bands beneath, except at the bases of the pilasters. The left side elevation has four bays of tall round-arched windows set in shallow recesses, with similar detailing to the right side, although partially obscured by the earlier schoolroom wing.

The schoolroom is single-storey, stuccoed, and has a hipped roof of artificial slate. It has four bays, with a door in the left bay and three twelve-pane sash windows to the right, set within round-arched openings; the present sashes likely replaced earlier round-headed glazing.

The chapel interior features a three-sided gallery with long panels and an applied grained finish, supported by plain iron columns. Box pews face inwards towards the side bays. A large, serpentine-fronted pulpit has decorative cast-iron slat balusters, a panelled base, and side stairs. The pulpit is likely slightly later and may have been updated after the 1859 Revival to accommodate a raised platform for more dynamic preaching. A rear arch behind the pulpit has had its moulding removed. Two tall round-arched windows have been blocked up behind the pulpit. The ceiling is boarded and ribbed, with a deep plaster cove and a large central plaster rose. The undersides of the galleries have been boxed in at the pulpit end to create small vestries, with timber arcading and leaded glazed partitions within. A significant seat has been altered. The rear lobby has a sliding sash window with marginal glazing and a central latticed pane. There are several early monuments, including those for Edwin Hughes (died 1831) and family, and John Lewis (Registrar, died 1849) and Rev Robert Morris (died 1825). The monument to Robert Morris is signed by Edwards and Son, Merthyr, and features a shaped stone tablet with an elaborate carved surround, fluted tapering pilasters, a semi-circular top with carved books and text.

Within the schoolroom is a cut-down 19th-century pulpit, possibly the original installed by Thomas, with a painted canted front, long panels with blunt trefoiled heads, elongated quatrefoils above, and a bench with scrolled arms and a pedimented panelled rear board with fluted pilasters. A plaque from the earlier chapel, reading “Saron Independent Chapel. Built 1819. Rebuilt 1828”, has been reset in the schoolroom vestibule.
