Sirhowy Ironworks

Sirhowy Ironworks is a significant industrial site featuring the remains of a large rubble-built furnace bank situated against the hillside. This structure includes three high narrow arches with yellow brick heads, which create openings in the retaining walls and are supported by brick barrel vaults. There is a parallel barrel-vaulted passage located at the rear of the furnace bank, accessible through round-arched doorways. The left-hand and central arches are similar, both having rubble rear walls. A passage leads off from the left arch, branching into two lower cross-passages, with a communicating arch between the tunnels. The middle tunnel features a circular oculus, and in front of its arch sits a low circular brick furnace base topped with a large piece of slag. In front of the left arch, there are brick footings. The right-hand arch is notably taller and shallower, characterized by a semi-elliptical arch at the rear, which has a filled-in rear shaft and arched side openings that are largely obscured by debris. Although much of the masonry above the arch-rings has been lost, two small rubble-vaulted culverts can be found above, one of which contains a large cast-iron pipe.

To the south, in the hillside, there are remains of another furnace, which consists of the base of a slag-lined crucible along with the footings of a rectangular brick structure. To the northwest, remnants of a stone building are present, featuring the mouth of a stone-lined barrel-vaulted tunnel facing south, located above 20th-century garages. In the northeast corner of the site, the foundations of a small rubble-built structure can be seen, which includes the mouth of a stone-lined conduit.
