Coity Sandstone Quarry and Incline is a post-medieval and modern quarry in Wales, protected by Cadw under reference MM279. The site exploits the South Wales Upper Coal Measures Formation, a Westphalian-age sequence of mudstone, siltstone, sandstone, coal, ironstone and ferricrete that underlies the location. The quarry's primary target was the sandstone beds within this formation, which provided a valuable building and industrial material.
The incline feature indicates a designed system for transporting extracted stone down the slope, a common engineering solution in quarries where topography allowed gravity-assisted haulage. Such inclines were typically constructed with wooden or iron track-work to move loaded wagons or sledges. This infrastructure reflects the industrial intensification of stone extraction across South Wales during the nineteenth and twentieth centuries.
The quarry remains an important archaeological record of Welsh industrial heritage, preserving evidence of extraction techniques, transport infrastructure and economic activity tied to the region's coal and mineral resources. The visible geology of the working faces documents the Westphalian succession and the quarrying strategies employed to access and remove the most commercially valuable stone bands within the sequence.
