About Efra-Hvolshellar
Efra-Hvolshellar are a trio of fascinating man-made caves in South Iceland, notably including one of the country's longest at 45 meters. Named 'Irish Caves', their age may predate the Norse settlement, hinting at early inhabitants. Recent efforts have improved access to these protected historical sites.
History & Background
The Efra-Hvolshellar caves, known locally as Írahellar or 'Irish Caves', hold a unique place in Icelandic history. While many man-made caves in Iceland were constructed in the 19th century, the ancient naming of these particular caves strongly suggests an origin predating the Norse settlement of Iceland around 874 AD. This makes them incredibly rare and significant archaeological sites, potentially offering evidence of early Celtic or Irish inhabitants before the arrival of the Vikings. Comprised of three distinct chambers—two interconnected and one solitary—the caves were likely used for shelter or storage by early settlers. The standalone cave, estimated at 45 meters, once held the title of the second-longest man-made cave in the country. However, a collapse of a built roof opening approximately a century ago filled much of its interior with soil, limiting current access to about one-third of its original length. Despite this, the site is carefully protected, and recent work has aimed at improving accessibility while preserving its historical integrity, allowing visitors to connect with Iceland's enigmatic pre-settlement past.
