The geological history of Þingvellir National Park is forged in the fire of volcanoes and the cooling stresses of glacial immersion, torn by the effects of continental drift.
Þingvellir or Parliament Plains, is the site of Iceland's AlÞing general assembly from Ca. 930 - 1798.
The site at which in 1000, the pagan Law Speaker, Þorgeir Ljosvetninggagooi was given the decision to choose the religion of which all Icelanders should worship. Choosing Christianity, he united a population that had previously been divided by religious belief in which both pagans and christians had set up alternative laws and parliaments refusing to acknowledge each other's laws.
