Rangárvallasýsla
Rangárvallasýsla is a historical county in southern Iceland. Its name derives from the Rangá river system, which flows through the region. Geographically, it is situated within the southern part of the island, a landscape characterized by fertile farmlands and a coastline along the Atlantic Ocean. Historically, this area was a significant agricultural region, known for its sheep farming and dairy production. The county encompassed several smaller districts and settlements. Notable geographical features include the Eyjafjallajökull volcano, which famously erupted in 2010, and the Hekla volcano, one of Iceland's most active. The landscape is also marked by numerous waterfalls and glacial rivers. Rangárvallasýsla was a self-governing administrative unit for centuries before the administrative reforms in Iceland. Today, the area is largely encompassed by the larger municipalities of Rangárþing eystra and Rangárþing ytra, retaining its historical and geographical significance within the modern administrative structure of Iceland. The region continues to be a vital part of Iceland's agricultural heartland and a popular destination for tourists drawn to its natural beauty and historical sites.
