Treffry Viaduct is a combined viaduct and aqueduct constructed in the 1830s to carry both a mineral railway and fresh water across the Luxulyan Valley in Cornwall. Built of granite, the structure comprises a series of substantial arches that span approximately 215 metres in length and rise to a considerable height above the valley floor, exemplifying the engineering capabilities of the industrial period. The viaduct was designed to serve the tin and copper mining operations in the locality, facilitating the transport of minerals whilst simultaneously conveying water for use in the mines and associated industrial processes. Its hybrid functionality and robust construction make it a significant example of Victorian industrial engineering within the Cornish landscape, reflecting the scale of investment in regional mineral extraction during the nineteenth century.
