Thingvellir National Park

Bláskógabyggð

The park is situated within a rift valley, a geological feature created by the divergence of tectonic plates. This unique geological setting has resulted in a landscape characterized by dramatic cliffs, deep canyons, and crystal-clear lakes. One of the most striking features is Almannagjá, a 7-kilometer-long rift valley that serves as a stark reminder of the Earth's tectonic activity. The canyon's walls are composed of basalt, a volcanic rock that lends a dark, rugged beauty to the landscape.  


Another remarkable geological feature is the Silfra Fissure, a submerged rift valley that connects Thingvellir National Park to Lake Thingvallavatn. The fissure is filled with glacial water that has been filtered through volcanic rock for centuries, resulting in exceptionally clear and pure water. Snorkeling and diving in the Silfra Fissure offer a unique opportunity to explore the underwater world between two continents. The visibility in the water is so clear that it's possible to see the colorful volcanic formations and the vibrant aquatic life.

Historical Significance

Beyond its geological wonders, Thingvellir National Park holds immense historical significance. In 930 AD, Icelanders established the Alþingi, their national parliament, at this location. The Alþingi continued to convene in Thingvellir for over 800 years until it was moved to Reykjavik in 1798. The park served as the heart of Icelandic democracy for centuries, where laws were passed, disputes were settled, and leaders were elected.  


The origins of the Alþingi can be traced back to the early 10th century when Viking settlers began to inhabit Iceland. As the population grew and communities formed, the need for a central governing body became apparent. It was in the year 930 that a group of influential leaders, led by Þorgeir Ljósvetningagoði, established the Alþingi at Thingvellir. Thingvellir, a valley located between two tectonic plates, offered a natural amphitheater for the assembly. Its dramatic landscape, with towering cliffs and a rushing river, provided a fitting backdrop for the momentous gatherings that would take place there.  


The Alþingi served as both a legislative and judicial body. Laws were proposed, debated, and enacted by the assembly, and disputes were settled through legal proceedings. The Lawspeaker, a respected individual elected to preside over the Alþingi, was responsible for reciting the laws from memory and ensuring that they were upheld. One of the most significant decisions made by the Alþingi was the adoption of Christianity in the year 1000. This momentous event marked a turning point in Icelandic history, as it brought the nation into the broader European cultural sphere.


The decline of the Alþingi began in the late 13th century, when Iceland fell under the rule of the Norwegian Crown. Although the assembly continued to meet at Thingvellir, its powers were gradually eroded. The Norwegian king appointed a governor to oversee Iceland's affairs, and the Alþingi was reduced to a largely ceremonial function. The Danish Crown later replaced the Norwegian Crown as the ruling power over Iceland, and the Alþingi's authority was further diminished. However, the assembly remained a symbol of Icelandic identity and a source of hope for the nation's independence.


In 1944, Iceland declared its independence from Denmark and established a republic. The Alþingi, now the sole legislative body of the nation, has continued to play a vital role in shaping Iceland's political and social landscape.  Today, the Alþingi meets in Reykjavík, the nation's capital. Although it no longer convenes at Thingvellir, the historic site remains a powerful symbol of Iceland's heritage and a popular tourist destination.

Ecological Importance

Thingvellir National Park is also an important ecological area. The park is home to a diverse range of flora and fauna, including many endemic species. The surrounding forests and meadows provide habitat for a variety of birds, mammals, and insects. The park's lakes and rivers are also important for fish populations, including trout and salmon.


  The flora of Thingvellir is characterized by its resilience to harsh environmental conditions. The park is home to a variety of Arctic and subarctic plant species, including birches, willows, heathers, and sedges. These plants have adapted to the cold, windy climate by developing small, leathery leaves and shallow root systems. The vegetation in Thingvellir plays a crucial role in the ecosystem, providing food and shelter for a variety of animals.  


The fauna of Thingvellir is relatively diverse, considering the park's remote location and harsh climate. The most common mammals in the park are Arctic foxes and brown rats. These animals are well-adapted to the cold and can survive on a diet of small rodents, birds, and insects. The park also supports a variety of bird species, including ducks, geese, and gulls. These birds migrate to Thingvellir in the summer to breed and raise their young.  


One of the most unique features of Thingvellir's ecology is the presence of endemic species. These are species that are found nowhere else on Earth. The most famous endemic species in the park is the Arctic char (Salvelinus alpinus). This fish has evolved into several distinct subspecies in Lake Thingvallavatn, each with its own unique characteristics. The Arctic char is a valuable food source for humans and other animals in the region.


The park's unique geological features and pristine waters have made it a popular destination for scientific research. Scientists have studied the park's geology, ecology, and hydrology to gain a better understanding of the Earth's processes and the importance of preserving natural environments.
