Sirhowy Ironworks

The remains largely consist of a massive rubble-built furnace bank, built against the valley-side. This contains three high narrow arches with yellow brick heads, puncturing the retaining walls as brick barrel vaults. Parallel barrel-vaulted passage to rear of furnace bank, accessed by round-arched doorways. The left-hand and centre arches are similar, both with rubble rear walls. Passage to left of left arch, off which branch two lower cross-passages. Communicating arch between tunnels. Middle tunnel has circular oculus: in front of arch is low circular brick furnace base, with large lump of slag on top. In front of left arch are brick footings. The right-hand arch is much taller, and shallower, with a semi-elliptical arch to the rear, with filled-in rear shaft and arched side openings (much obscured by debris). Much masonry has been lost above the arch-rings, but set above are two small rubble-vaulted culverts, one containing a large cast-iron pipe.

To the S, in the hillside, are the remains of another furnace, consisting of the base of a slag-lined crucible, with footings of brick rectangular structure. To the NW are the remains of a stone building, with the mouth of a stone-lined barrel vaulted tunnel facing S, over C20 garages. In the NE corner of the site, the foundations of a small rubble-built structure, including the mouth of a stone-lined conduit.
