The Niarbyl Fault is an exposed section of the Iapetus Suture, a fault caused by the collision of two ancient tectonic plates – Avalonia on which present-day England is located and Laurentia which contains North America and parts of Scotland – that extends across the Irish Sea. The fault is visible close to the shoreline downhill from the Niarbyl Cafe and Visitor Centre in Niarbyl; you can place each foot on different rocks derived from two separate continents. The area also offers a hidden bay and dramatic coastal path with views across to the Mountains of Mourne in Ireland on a clear day and along the Manx coastline to the Calf of Man. One of the fishermen’s cottages here was used as Ned Devine’s cottage in the 1998 film Waking Ned.
