Svartalfheim is the underground realm of tunnels and forge-fire that the dwarves call home. Its craftsmen hammered out some of the gods' most prized possessions, from Thor's hammer to Freyja's necklace, working matter that traces back to the body of the first giant.

Home of the dwarves

Snorri Sturluson's Prose Edda names Svartalfheim, home of the black elves, as the realm of the dvergar, the dwarves. Unlike the bright world of Alfheim above, Svartalfheim is a world of darkness and stone, reached by descending rather than ascending, its people small, skilled, and rarely willing to leave their tunnels for long. No single myth is set entirely within its borders, but its craftsmen reach into nearly every other realm through the objects they send out into the world.

Origin in Ymir's flesh

The Prose Edda's Gylfaginning gives the dwarves an origin unlike any other Norse race: they first bred as maggots in the rotting flesh of Ymir, the primordial giant whose body the gods later used to build the world itself. The gods gave these creatures human understanding and shape, but let them keep their dwelling underground, in earth and stone, which is why Svartalfheim's tunnels suit them so naturally.

Treasures of the forge

The dwarves' greatest fame comes from a single contest recorded in the Prose Edda's Skaldskaparmal, in which Loki wagered his own head that one pair of dwarven smiths could not outdo another.

Common questions

The realms, roots, and beings of the Norse world - answered.

What is Svartalfheim?

Svartalfheim is one of the nine realms of Norse cosmology, an underground world of tunnels and forges home to the dwarves. Its name means home of the black elves, and Snorri Sturluson treats its people as the same beings elsewhere called dvergar, or dwarves.

What did the dwarves of Svartalfheim make?

The dwarves of this realm forged some of Norse myth's most famous treasures: [Thor's](/blog/gods/thor/) hammer Mjolnir, [Odin's](/blog/gods/odin/) spear Gungnir, the ship Skidbladnir, the ring Draupnir, and Brisingamen, the necklace of [Freyja](/blog/gods/freyja/). The Prose Edda's Skaldskaparmal tells the story of Loki wagering his head on the contest between two pairs of dwarven smiths that produced these gifts.

Are svartalfar the same as dwarves?

Snorri Sturluson uses the terms svartalfar (black elves) and dvergar (dwarves) close together and largely interchangeably, and most later tradition treats Svartalfheim as the dwarves' home realm. Some scholars argue the two labels reflect a genuine older overlap between elf and dwarf as categories rather than one Snorri simply invented.

How were the dwarves created?

The Prose Edda's Gylfaginning says the dwarves first bred like maggots in the flesh of the primordial giant Ymir, and the gods then gave them human shape and understanding, along with a dwelling in the earth and in stone. Their underground craft in Svartalfheim follows from this origin in dead matter beneath the world.

Is Svartalfheim the same place as Nidavellir?

The two names appear together in the sources without a clear distinction drawn between them, and most interpreters treat Nidavellir, meaning dark fields, as another name for the dwarves' underground realm, whether or not it is strictly identical to Svartalfheim in every text.
