Þingvellir (Thingvellir) National Park is a UNESCO world heritage area and home to Iceland's first parliamentary assembly called Althingi. The initial two-week meeting in the month of June in 930 CE marked Iceland's birth. The sessions continued until the year 1798 when it was then replaced by the High Court until it was reinstated about 50 years later. Ruins of the ancient stone "booths" are still visible and visitors can walk between two tectonic plates.[1] Visitors can look out from the uplifted tectonic ridgeline and see the numerous fissures varying in size as well as the Silfra fissure.
