At Keldur in Rangárvallasýsla, there is an old turf farm which, despite its age, is one of the largest preserved turf farms in south Iceland. The wooden frame of the hut is characteristic of Roman style. From the hut there is an underground tunnel thought to date from the 12th or 13th century and was probably built during a time of conflict. In addition to these, several outhouses have been preserved. Open daily from June 1st – August 30th from 10:00-17:00.
