The monument comprises the remains of the iron works at Furnace, which sit within the village on the shore of Loch Fyne. The monument was first scheduled in 1965. On this occasion, an imprecise area was defined: the present rescheduling rectifies this.

The ironworks at Furnace was founded by the Duddon Co. from Cumbria in 1755, under a 57-year lease from the Duke of Argyll. The company was attracted by the plentiful supplies of charcoal to be found in Argyll. Production ceased in 1812 with the expiry of the lease. It is possible that several of the later alterations to the buildings relate to the Loch Fyne Powder Works, which were founded near by in 1841.

The remains of the ironworks consist principally of the furnace, a casting house, a three-storey blowing house, a large storage shed (now used as a coal-store), the traces of a lade and the remains of an enclosure, probably a reservoir, which has been recently demolished. The storage shed, lade and enclosure are not included within the scheduled area.

The furnace is a remarkably complete tapering square blast furnace, built of locally quarried granite incorporating many courses of roughly-squared blocks divided by small thick pinnings, set in lime mortar. It has retained its central hearth, built of light red sandstone, and brick lining which is intact, a unique survival. The ground floor of the furnace stack has two lintelled embrasures, one for the bellows and one for tapping off the molten metal into the casting house. These are formed with cast iron lintels, one of which is inscribed GF 1755, for Goatfield Furnace. Access from the terrace to the loading mouth was via a substantial stone-revetted ramp and the bridge loft on the upper floor of the blowing-house. The ground floor of the blowing house contained the bellows powered by a water wheel, fed from the lade. The casting house is a one-storey structure, now roofed with corrugated iron.

The area to be scheduled includes the furnace, the blowing house , the casting house and an area around it that has the potential for associated archaeology. The area is irregular in shape and has maximum dimensions of about 42m NNW-SSE and 37m NE-SW as marked in red on the attached map.

About Scheduled Monuments

Historic Environment Scotland is responsible for designating sites and places at the national level. These designations are Scheduled monuments, Listed buildings, Inventory of gardens and designed landscapes and Inventory of historic battlefields.

We make recommendations to the Scottish Government about historic marine protected areas, and the Scottish Ministers decide whether to designate.

Scheduling is the process that identifies, designates and provides statutory protection for monuments and archaeological sites of national importance as set out in the Ancient Monuments and Archaeological Areas Act 1979.

We schedule sites and monuments that are found to be of national importance using the selection guidance published in Designation Policy and Selection Guidance (2019)

Scheduled monument records provide an indication of the national importance of the scheduled monument which has been identified by the description and map. The description and map showing the scheduled area is the legal part of the scheduling. The statement of national importance and additional information provided are supplementary. These records are not definitive historical or archaeological accounts or a complete description of the monument(s).

The format of scheduled monument records has changed over time. Earlier records will usually be brief. Some information will not have been recorded and the map will not be to current standards. Even if what is described and what is mapped has changed, the monument is still scheduled.

Scheduled monument consent is required to carry out certain work, including repairs, to scheduled monuments. Applications for scheduled monument consent are made to us. We are happy to discuss your proposals with you before you apply and we do not charge for advice or consent. More information about consent and how to apply for it can be found on our website at
