Treffry Viaduct

Treffry Viaduct is a granite bridge in Luxulyan Valley that served both as a railway crossing and a water conveyance system. The structure has two separate levels: the upper one carries rail traffic while the lower channel transported water for industrial operations.

The structure was built between 1839 and 1842 by Joseph Thomas Treffry to transport minerals and water for mining operations. It was designed as an engineering solution to meet the industrial demands of Cornwall's mining industry during that period.

The viaduct stands as a reminder of Cornwall's mining era and the engineering solutions people created to solve practical problems. It shows how a single structure served both transportation and industrial needs in the region.

The structure is most easily reached on foot from Luxulyan village or from the Pont's Mill car park, where marked trails lead to the viaduct. Walking paths through the valley provide the best access and clear views of the monument.

The viaduct has an unusual dual function that was quite rare for its time: a railway line on top and a complete water channel below. This combination was an ingenious way to maximize the use of a single structure for two critical industrial needs.
