MYLOR PERRAN WHARF Engineers shop

(formerly part of group listed as Perran)

30.5.67

GV II* Engineers shop, boring mill and pattern shop, now store. Circa early-mid C18 and partly enclosing earlier structure possibly late C18. Painted rubble walls with brick arches and wooden lintels. Corrugated asbestos and scantle slate roofs with gable ends and large stack at south side paragraph.

Overall plan survives since the C19, of large tapered single-storey working area covered by parallel roofs running east west; rectangular two-storey building with roof running north south adjoins at east end and further rectangular extension (originally pattern shop adjoins middle of west end).

This building's machinery was driven by two waterwheels turned by water from leat passing parallel to south and discharged into river parallel to north side. Wheels and machinery since removed. Many original openings survive, wide and narrow doorways, including openings at north gable end to ground floor, first floor and to gable. Many first floor window openings with some window frames covered in P.V.C. sheeting.

Interior has original roof structures of both king post and queen post type.

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).

Despite superficial C20 alterations, this is a very complete C19 industrial building.
