The boat leaves the western jetty, known as Raynes Jetty, at Llanddulas, North Wales. The limestone aggregates are exported from Raynes Quarry to various locations in the UK and the near-continent for use in the construction and chemical industries. Vessels up to 5000 dwt are loaded. Llanddulas Quarries have a history dating back to at least 1284 AD when the Bishop of Bangor was awarded the right to quarry the limestone from Llanddulas as a fee for christening the young King Edward 1 of England.
