This gem in South Iceland is a unique natural landmark. It is located near the Eyjafjöll mountains, by the ring-road one and thus easily accessible. Said to be the largest man-made cave in Iceland, Rútshellir has two parts. The upper half contains an adjoining cave, which is so high that at one time, a 2nd floor was installed, making this a double-story cave. Further in, there is a ledge that was undoubtedly used for sleeping. In the ceiling, you will notice a carving of a cross that tells us that the cave dates from the time of Irish monks, before the Norse settlement. Many legends are connected to this cave. One involves a man called Rútur, who lived in the cave, but his slaves intended to kill him. They carved a hole under the ledge where Rútur slept, so they could kill him with spears while he was asleep. One night, arriving home and preparing to sleep, Rútur discovered their plot and chased the enslaved people into the mountains and killed them all. Sorry about the horror story - it's a fun place to visit, I promise! Definitely an interesting spot for a quick leg stretch along the south coast.
