MYLOR PERRAN WHARF Dry Sand shop and Green Sand shop

(formerly part of group listed as Perran Foundry)

30.5.67

GV II* Mould and casting buildings, now store. Circa early-mid C19. Painted shale rubble walls, brick arches. Three roofs with gable ends or adjoining; grouted scantle slate over main block (Dry Sand shop) with upper half of west gable weather boarded; clay pantiles over Green Sand shop, adjoining at east; and corrugated asbestos over stove extension at west.

Plan of three roughly rectangular adjoining buildings. Main building (Dry Sand Shop) with spaces for furnaces (stoves) at east and west plus two later stacks each with two flues to north side. Single storey Sand Shop at east is narrower, and two storey stove extension at west, much narrower, and adjoins south side of gable of main building. There was originally a water wheel at south side of Dry Sand Shop. Two storeys. Dry Sand Shop has large round-headed arches to north and west walls, originally furnace entrances, except for central west doorway. Other arches are partly or wholly blocked or hidden by later building. West gable end has two first floor openings probably originally with windows. First floor of Stove has four of the original seven openings spanned by granite lintels. Original ground floor openings blocked.

Interior has original king post roof structures and much evidence of former use.

Part of the Perran Iron Foundry, founded in 1791, and in its heyday the most important foundry in Cornwall, manufacturing some of the largest beam engines ever constructed.

Plan of Perran Foundry, circa 1860 (CRC).

This is the main furnace building which in the C19 must have been both hot and dangerous. Now, with some of the 'stove' projections removed and with its brick arches standing alone, it is still quite impressive and surprisingly intact.
