Radyr Stone is a \u2018freestone\u2019, meaning it can be cut in any direction without breaking, and it is a local speciality produced from a number of quarries in Cardiff.

At the time of its deposition, sedimentation was influenced by the Triassic topography of hills and cliffs, which would have accumulated scree at their bases. The climate was hot and arid but occasional heavy storms produced flash flooding that created wadis and transported mainly Carboniferous-aged sandstone and limestone pebbles and cobbles (\u2018clasts\u2019). The clasts were deposited in large alluvial fans, which are visible in the bases of the thick beds in the quarry. <\/p>\n\n\n\n<p>The clasts are contained within a red matrix with a calcareous (calcium carbonate) cement. The sediments become finer grained upwards, illustrating the decreasing speed of flow of the storm-influenced rivers. The repeating pattern of decreasing grain size indicates multiple storm events.&nbsp;&nbsp;&nbsp;&nbsp; <\/p>\n\n\n\t\t\t\t<div  class=\"owl-carousel carousel-primary-color carousel owl-theme thumbs-carousel-js\">\n\t\t\t\t\t<div class=\"item\"><figure  class=\"img-wrap\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/11\/RadyrQuarry_closeup2_web.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;Close up of the Radyr Stone showing the pebbles and gravel conglomerate. \u00a9 Rhian Kendall.&lt;\/p&gt;\n\" data-gallery=\"gallery_36548\"><img decoding=\"async\" src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/11\/RadyrQuarry_closeup2_web.jpg\" class=\"attachment-medium size-medium\" alt=\"Radyr Quarry close up\" \/><\/a><figcaption class=\"caption sm-line\">\n\t\t\t\t\t<div class=\"caption-icon\">\n\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.bgs.ac.uk\/wp-content\/themes\/bgs\/img\/info-caption.svg\" alt=\"Information icon\">\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"caption-text\"><p>Close up of the Radyr Stone showing the pebbles and gravel conglomerate. \u00a9 Rhian Kendall.<\/p>\n<\/div>\n\t\t\t\t\t<div class=\"expand-box expand-box-top\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/11\/RadyrQuarry_closeup2_web.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;Close up of the Radyr Stone showing the pebbles and gravel conglomerate. \u00a9 Rhian Kendall.&lt;\/p&gt;\n\" data-gallery=\"gallery_36548\"><img decoding=\"async\" src=\"https:\/\/www.bgs.ac.uk\/wp-content\/themes\/bgs\/img\/expand.svg\" alt=\"Expand icon\"><\/a><\/div>\n\t\t\t\t<\/figcaption><\/figure><\/div>\t\t\t\t<\/div>\n\t\t\t\t\n\n\n<h2 class=\"wp-block-heading\" id=\"quarry-and-examples-of-use\">Quarry and examples of use<\/h2>\n\n\n\n<p>Radyr Stone was quarried from a number of locations across Cardiff from the 1850s to the 1920s. Radyr Quarry\u2019s main period of extraction was from around the 1850s up to until 1908, although it did supply stone for Insole Court in Llandaff during the First World War. The quarry\u2019s position close to the railway line meant that the stone could be easily transported; for example, the stone was taken to build Penarth Dock as well as a number of local bridges along the Taff Vale Railway.<\/p>\n\n\n\n<p>To the south of Hermit Woods is another area of parkland called Hailey Park. Here you can see an example of Radyr Stone used in the five-arched Taff Vale Railway Bridge, which crosses the River Taff. It was designed by Isambard Kingdom Brunel and is now a Cadw Grade II listed structure. The early parts of the bridge were built in locally sourced Radyr Stone, quarried on the west side of the railway just opposite the park.<\/p>\n\n\n\t\t\t\t<div  class=\"owl-carousel
