Plough United Reformed Church

The Plough United Reformed Church is a large chapel built in the 19th century, featuring a combination of pebbledash and smooth render with painted stone dressings. The main elevation facing Lion Street includes a pediment with blind arcading in the tympanum, adorned with a terracotta finial and balustrades. Below the pediment, there are three round-headed window openings with keystones and pilasters, each containing round-headed sash windows with margin lights. The ground floor features a pedimented porch flanked by pedimented bays, with the porch's pediment supported by a pair of narrow fluted columns in antis. Each flanking bay has a paired two-pair round-headed window. The north-western return of the building is two storeys high and consists of three bays with horned small pane sash windows, while the south-eastern return is similar. At the rear, there is a lower block with a sloping roof.

Inside, the church boasts a magnificent interior with rich woodwork. The elaborate panelled ceiling features concentric roses and floral panels in the spandrels. A balcony encircles all four sides of the chapel, supported by fluted iron columns. The balcony front has arcading with floral relief decoration and arched panels flanked by ebonised columns, along with a clock. There are fitted pews, including curved ones along the sides, and a large pipe organ. The set fawr enclosure is finished with wooden panelling and has an arcade above the panels, leading to a semi-octagonal pulpit with arched panels and floral decoration, also supported by ebonised columns. A stained glass panel depicting ploughing adds to the interior's charm. The wooden stairs leading to the gallery feature turned newels, and the floors are tiled. The vestry at the rear has a plaque stating "Welsh Independent Chapel Built 1841 On Premises First Appropriated To Protestant Dissenters in 1699," along with other mid-19th century marble memorials that were transferred from a former chapel in Glamorgan Street when the congregations merged in 1923.
