Liscannor, County Clare
This sandstone was deposited around 320 million years ago on an ancient offshore river delta. The rocks have preserved a multitude of feeding trails, left behind by an unknown organism.
The sandstone is extracted in flat slabs, known as ‘flags’ in the quarrying industry, and has been used extensively as flooring and building stone. This stone is commonly used for fireplace hearths in Ireland.
Smaller pieces of Liscannor Flagstone have also been used by the landscapers to provide margins to the gravelled/planted areas around each stone here in the geology garden.
The tall flagstones that you see in the garden were extracted from the Liscannor Stone Quarries near the famous Cliffs of Moher in County Clare.
