In southwestern Iceland Þingvellir National Park geological forces meet human history.
The Birthplace of Democracy
In 930 CE, Icelandic chieftains gathered at Þingvellir to establish the Alþingi, one of the world’s oldest parliaments. For centuries, this outdoor assembly met annually at Lögberg (Law Rock), where laws were recited, disputes were settled, and the nation’s fate was decided.
In 1000 CE, it was here that Icelanders made the momentous decision to adopt Christianity, averting civil war through compromise rather than conflict.
In 1262, they yielded authority to the Norwegian King. After this, the assembly continued to meet, but their power diminished. The last assembly here in Þingvellir took place in 1798.
Five Must-See Wonders from Icy Betrayals
Walk between two continental plates along this dramatic rift valley. The pathway through Almannagjá offers the experience of literally standing between North America and Eurasia as they drift apart at about 2 centimeters per year. The gorge is approximately 7.7 kilometers long and up to 64 meters wide in places. The walls tower 40 meters high on either side of the walking path. This split formed from thousands of years of tectonic activity and earthquakes. The last major earthquake here was in 1789, which dropped the valley floor by about one meter overnight.
The first time we visited (April 2024) the landscape was still snow-covered. And the walkways hadn’t quite melted, so we (and others) were clutching the handrail on our way down between the rocky cliffs – hence the lack of photos. On our second visit (Sept. 2025), I stopped for a photo. It was cold up at the top of the gorge, but as we descended, the cliffs blocked the wind.
Iceland’s largest natural lake covers 84 square kilometers. Underground springs feed the lake with water that has filtered through porous lava rock, which is why the water stays crystal clear year-round. Silfra, a deep fissure at the edge of the lake, makes for a popular place to snorkel between the two tectonic plates. The water temperature remains cold, between 4-10°C depending on the season.
Though the exact location remains debated by historians, the marked site of the Law Rock is where the Lawspeaker recited Iceland’s laws from memory to the assembled crowd. The position was created in 930 CE and continued until 1271. From this rock, major announcements were made that shaped Iceland’s future, including the declaration of independence from Denmark in 1944, when thousands gathered to hear the proclamation at this historic site.
Scattered across the plains are the remnants of temporary booths where Viking-age Icelanders camped during the two-week assembly. Chieftains and their retinues erected turf-and-stone shelters, creating a temporary tent city that could house hundreds. These ancient camping spots, visible as low stone foundations, show where deals were brokered, marriages arranged, and alliances forged around campfires under the midnight sun.
This pool in the Öxará River serves as a chilling reminder of medieval justice. Between 1602 and 1749, women convicted of crimes like adultery, infanticide, or perjury were drowned here, tied in a sack and submerged in the frigid waters. Men faced beheading instead. It’s a sobering testament to Iceland’s harsh past. Have a look at the video I took of this pool.

WHY set a critical scene upon Law Rock? Because when Iceland finally won independence from Denmark, this is how they celebrated:
