New Bethel Chapel

New Bethel Chapel is a 19th-century chapel oriented east to west, with its entrance on the east and the interior facing west. The building is constructed of stone, mostly rendered, with rock-faced dressings, and features a half-hipped Welsh slate roof over the gable end facade. At the gallery level, there is a tripartite central window flanked by one window on each side, with rock-faced surrounds that create a cohesive pattern across the facade. The window glazing has all been replaced with modern materials. The ground floor includes a very wide central doorway with double doors and flanking windows, all set beneath adjoining rock-faced lintels, and features rock-faced quoins. The sides of the chapel have similar windows and rendered buttresses, while the rear has long paired windows with rock-faced and tooled surrounds.

Inside, the chapel retains its gallery, which has a panelled front and a boarded soffit, supported by cast iron columns. The hallway is boarded, with stairs on either side leading up to the gallery, and the woodwork is grained. The original ceiling is covered. On the walls are plaques dedicated to former ministers, including one for the founder Thomas Waters, who died in 1794 and is buried in the cemetery by the rear wall; however, the church was extended over his grave, which now lies beneath the pulpit. There is also a plaque for Rev Thomas Harries of Kidwelly, who died in 1837, as well as some other plaques that have been relocated from the former Jerusalem chapel in Blackwood.
