Former Llanarthney National School

Single-storey school building in local sandstone with slate roof. The front and the right gable are built in ashlar in graded courses, elsewhere the masonry is uncoursed and hammer-dressed. The roof has a slight projection at eaves and verges. The front elevation (towards the yard) consists of three windows, each of three lights, with a flat arch head and a Tudor label-mould. Each light is of two panes, with a four-centred head. Sandstone sills. At the left is a low-roofed later porch partly in randomly coursed ashlar, boldly projecting. It has a boarded door beneath a straight-sided pointed arch. Each gable end has a tall window of two lights with a four-centred arch and a label mould. Rendered C20 extensions at rear. One small original iron gate survives at the rear.
