Description

This is a row of arsenic calciners, now disused, located approximately 250 meters south-west of Clematis and Penleat Cottages in Stoke Climsland. Built in the late 19th century, the structure is made of roughly coursed slate-stone with granite quoins and features red brick segmental arches. The row consists of two lines, about 90 meters long, forming a total of seven calciners that are open at the top. A front revetment wall with sloping buttresses remains at the eastern end. These calciners were used for roasting arsenic ore and expelling gases, and they are associated with the Luckett Mines that were operational in the late 19th century.
