Elliðavatn, the largest lake in the vicinity of Reykjavík. Also a farm of the same name, where in the 18th century a Swedish–German baron, by the name of Hastfer, started a sheep–breeding station. On the Þinganes point and surrounding area by the lake remains have been found which confirm that the Kjalarnesþing meetings were held there of old, for a period at least. It might even have been there that they prepared to establish the Althing at Þingvellir in the year 930. Archeological digs there have brought to light important relics from as far back as the settlement.
