St Andrew's Presbyterian Church, including Gates and Railings to Street

This is an 1865-8 Calvinistic Methodist Chapel, designed by K W Ladd, an architect from Pembroke Dock. It is constructed of grey squared limestone, with red brick and Bath stone dressings, and has concrete tile roofs. The building is a striking example of Romanesque architecture combined with North Italian Gothic detailing, featuring a two-storey facade with twin towers raised on a high basement.

The facade’s recessed central gable displays stepped red-brick corbelling under a coping, a large Bath stone date scroll, and a stepped triplet of arched windows with two-coloured heads beneath linked pointed hoods. Two thin, attached column shafts with carved capitals are also present. The wider central light has “Florentine” tracery. A red brick flush sill band runs around the towers. The ground floor contains paired arched doors, each with a column shaft between, similar coloured heads and pointed hoodmoulds. Plain arched lights are positioned on either side. The doors are heavily panelled with applied ironwork. Double flights of stone steps, seven steps from each side, lead to the entrance, with a broad set of seven steps also oversailing the basement area. The towers have a plain lower storey with a single arched light, and an upper storey recessed between angle piers with long, plain arched lights. They feature a red-brick impost band and red-brick zig-zag band near the top, under a red-brick eaves cornice with Bath stone brackets. The sides of each tower are similar in design.

The main chapel has five-bay sides with recessed bays between raised piers, and long arched window recesses with red-brick jambs and Bath-stone arches, stock brick filling the space between the upper and lower windows. The rear elevation is plain and rendered, with three arched windows.

Heavy spearhead front iron railings enclose the property, with two sets of more ornate gates set between stone piers with cross-gabled caps.

Inside, the chapel has a broad, flat ceiling with sloping side panels and deep arch braces resting on corbels. A boarded panel runs down the centre of the ceiling. A three-sided gallery is supported by iron columns with cast-iron trefoil-pattern pierced panels set between pilasters. An organ by J Conacher, installed in 1896, is housed in the rear gallery. The pulpit is accessed by right-angled stairs, with iron rails and a timber front featuring an inverted cone book rest. Behind the pulpit is an ornate three-light stained glass window from 1882, manufactured in London, and set within a pilastered, shallow gabled surround designed by KáMcAlpin. Two stained glass windows are located to the sides; one is signed W Morris, Westminster (date of death 1916), and the other is dated 1937 and was originally from the former Llanreath C M Chapel.
