Llandudno Great Orme Mines

The Great Orme (Welsh: Y Gogarth) is a limestone headland on the north coast of Wales, north-west of the town of Llandudno. Referred to as Cyngreawdr Fynydd by the 12th-century poet Gwalchmai ap Meilyr,[1] its English name derives from the Old Norse word for sea serpent.[2] The Little Orme, a smaller but very similar limestone headland, is on the eastern side of Llandudno Bay.
