230 years ago, Orrustuhóll was an islet in the middle of the swift flowing Hverfisfljót River. Then, in 1783, the Lakagígar eruption inundated the land with one of the largest lava flows in the history of Iceland. The river subsequently found its way back to the surface by forming streams and springs and the warm water is thought to have encouraged vegetation in the area that was once covered in black sand. The name Orrustuhóll is taken from the story of a battle of revenge, which took place on this mound,  where Hróar Tungugoði, ‘Hróar the wise god’  was avenged by his son Hámundur Halti.
