Cathedral is repaired with seaside rock

Test of dexterity: Quarry workers extracting sandstone from above St Bride's Bay in the Pembrokeshire Coast National Park, where the quarry that supplied the original material to build St David's Cathedral north of the bay in the 12th century has been reopened to provide for the restoration of the west front (inset).

Medieval methods of extraction are being used to avoid damage and pollution from blasting.
