Ingimundarhóll (Ingimundur’s Hill)
Ingimundur the Aged spent a winter in Víðidalur before he settled in the Vatnsdalur valley.
More: Ingimundur the Aged, emigrating from Norway to Iceland, made landfall in Borgarfjörður and spent a winter with Grímur at Hvanneyri. In the summer he went north, and found a valley where willow grew, and named it Víðidalur (Willowdale), and spent the winter there and built himself a longhouse.
Traces of a large longhouse exist at Ingimundarhóll just south of Vesturhópsvatn lake. A footpath leads from a heritage sign at the lake to the longhouse site, which is a listed heritage site.
