The Dimmuborgir area is composed of various caves and rock formations, remnants of volcanic activity that are perhaps reminiscent of an ancient collapsed citadel.
In Icelandic folklore, Dimmuborgir is said to connect earth with the infernal regions. In Nordic Christian lore, it is also said that Dimmuborgir is the place where Satan landed when he was cast from the heavens and created the apparent "Catacombs av helvelte" which is Icelandic for "The Catacombs of Hell".
The Norwegian black metal band Dimmu Borgir takes it name from the Dimmuborgir area. In late 2004 they played a benefit gig in the area for sufferers of cerebral palsy.
