Overview

History & significance

Alltwyllt Slate Quarry Incline is a Post Medieval and Modern period transport structure located in Meirionnydd, Wales, serving the slate quarrying industry that flourished in the region from the eighteenth century onwards. The incline represents a key example of the mechanical infrastructure developed to move slate from quarry workings down steep Welsh hillsides to processing areas or transport routes below. Such inclines employed rope-hauled or gravity-assisted systems to lower heavy loads efficiently across difficult terrain, a technological solution essential to the commercial viability of slate extraction in upland areas. The structure remains designated as a Scheduled Ancient Monument under Cadw's protection, reflecting its historical importance to understanding Post Medieval and Modern industrial heritage in Wales.
