Æðey, the biggest island in Ísafjarðardjúp, 1.26 km2, just off the Snæ­fjalla­strönd coast. One of the main breeding grounds of the eider duck in Ice­land, fertile, good landing place, pretty scenery. In 1615 some ship­wreck­ed Spanish sailors settled there. After they had been rather aggressive, Ari Magnús­son of Ögur attacked them with a force of men, killing them all dishonourably, some on Æðey, others at Sandeyri on Snæ­fjalla­strönd.
