Seion Capel y Bedyddwyr/Seion Baptist Chapel

Seion Capel y Bedyddwyr, a Baptist Chapel, is constructed from rubble stone and features a slate roof. The front, which dates to around 1897, is finished in unpainted roughcast with raised cement dressings. It has arch-headed windows on its two-storey front, with a central arch-headed door framed by a moulded architrave that includes a keystone. The entrance features paired, panelled doors and a traceried fanlight. The windows are set in channel rusticated frames with arched hoodmoulds, with larger outer windows and two slightly shorter windows in the centre of the first floor, which are positioned higher than the outer windows. Above these is a small traceried roundel. The upper windows include timber tracery with two lights and a plain circle above. The gable is coped and topped with a block finial, and there is a rectangular plaque that reads 'Seion Capel y Bedyddwyr 1843, 1897'. The chapel has angle pilasters with pedestal blocks above.

The side elevations, likely dating from 1843, are also made of rubble stone and feature a single window on each floor with cut stone heads. The end walls have arch-headed windows with cut stone voussoirs. Inside, the chapel has a wood boarded roof, a gallery, and pews.

The schoolroom, which may date from the early 20th century, incorporates a building with an external stair as marked on the 1908 Ordnance Survey 25 map. It is built from rubble stone with a slate roof and a west end stack. This single-storey structure has an arch-headed door and two windows on the forecourt elevation, with a rendered east gable end facing the road that features two arched windows. The timber windows have two-light tracery with a circle above. The door on the forecourt side matches the tracery of the fanlight and has ledged doors. The windows to the right have timber arched heads with paired fixed lights and top lights above, which may have been altered. To the north of the schoolroom, a low rock-faced stone wall runs with centre gatepiers, end piers, and iron spearhead railings, along with matching centre gates.
