Keldur is a farm and a church site in Rangarvellir County, South Iceland. Catholic churches there were dedicated to the apostle Paul. The present church was built in 1875. Where the old farm still stands in the shelter of the edge of the lava field, big cold springs, called Keldur, feed a stream. According to the Njal’s Saga, the farmer Ingjaldur Holskuldsson occupied Keldur around the year 1000. Later the most powerful dynasty of the country, the so-called Oddaverjar, had one of their manors there. The father of this dynasty, Jon Loftsson, spent the last years of his life there, and founded a monastery, which did not last very long. The hall of the old farm is very ancient, the oldest hall of the country.
1491 meter (4,892 feet) high Hekla is one of Iceland's most prominent, most known and active volcanoes. It has frequent eruptions that start with an explosive onset producing eruption plumes, then lava fountains and culminate in large lava flows. Most of the volcano's flanks are covered by extensive lava flows from historical eruptions, dating back to 1104 AD.
Icelandic folklore says this giant boulder was ripped from the mountains and placed at its current location, where it became home to elves.
