Dyne Steel Incline is a post-medieval and modern transport incline located in Wales, designated as a Scheduled Ancient Monument (SAM MM280) by Cadw. The structure represents industrial engineering associated with slate quarrying or mineral extraction operations characteristic of Wales's nineteenth and early twentieth-century extractive industries. The incline survives as physical evidence of the mechanical systems developed to transport heavy materials down steep terrain, utilising gravity-powered or steam-assisted technology typical of the period. Such inclines were essential infrastructure for connecting upland quarries and mines to valley-based processing facilities, rail networks, and markets.
