Horeb Brickworks was founded in 1907 as the Blackthorn Brick Works Co, it was renamed in 1914 as the Eclipse Brick Co Ltd, and again in 1926 when it became the Horeb Brick Co Ltd. It closed in 1980.
The extant building include the remains ofa 16-chamber Hoffman brick kiln, now listed (see NPRN 275711). It is believed to be the only example surviving in Wales. The bricks were moulded in the shed to the west, fired, and despatched to the railway siding to the east.
The moulding and drying shed serving the kiln has almost totally disappeared, but there are ruins to the NW of the kiln of an engine house. The claypit was about 100 m to the NW, and the engine house probably worked a tramway with chains.
