Ironstone Quarries at Carreg Maen Taro is a post-medieval and modern extraction site in Wales, protected by Cadw as monument MM295. The quarries exploited ironstone deposits within the Pennine Middle Coal Measures Formation and South Wales Middle Coal Measures Formation, sedimentary sequences of Moscovian age that underlie the site. These strata comprise mudstone, siltstone, sandstone, coal and ironstone, interbedded with ferricrete, minerals that formed in ancient tropical deltaic environments. The extraction of ironstone here reflects the region's industrial heritage, as such deposits were vital raw materials for iron smelting and steel production throughout Wales's industrial development. The quarried landscape preserves evidence of these extraction methods and the geological resources upon which local industry depended.
