Cleit an t-Sionnaich is a sea cliff or coastal rock feature located in the Outer Hebrides, likely composed of Lewisian gneiss, one of the oldest rock formations in the UK, dating back over 2,700 million years. These metamorphic rocks formed deep within the Earth's crust through intense heat and pressure and are notable for their durability and role in the geological history of the region.
