In the Norse cosmos, the gods do not live in a cloud or in an abstract divine realm. They live in a place — a real, physical place with walls and halls and streets and fields, built on a foundation of earth and rock, connected to the rest of the nine worlds by a rainbow bridge.
Asgard is the home of the Aesir, the primary family of Norse gods. It is one of the nine worlds that make up the Norse cosmos, arranged through the branches and roots of Yggdrasil, the world tree. And it is, like everything in Norse mythology, more complicated and more interesting than a simple "heaven for gods" summary suggests.
Where Is Asgard?
Asgard sits at the top of the cosmic structure, connected to Midgard — the human world — by Bifrost, the rainbow bridge. Bifrost is guarded by Heimdall, the watchman of the gods, who can see and hear across vast distances and whose horn Gjallarhorn will sound to signal the beginning of Ragnarök.
The precise geography of the nine worlds varies between sources. In some versions, Asgard is presented as elevated above or separate from Midgard. In others, the connection via Bifrost is described as crossing a sky. What's consistent is the bridge, the guardian, and the idea that Asgard is both accessible (gods travel freely) and protected against uninvited entry.
How Asgard Was Built
The walls of Asgard were built by a giant — and the story of that construction is one of the best-known trickster tales in Norse mythology. A builder came to the Aesir and offered to build walls so strong that no giant or troll could breach them, in exchange for the sun, the moon, and the goddess Freyja.
The gods were tempted but cautious. Loki suggested they accept the deal, but add conditions: the work must be finished in a single winter, the builder gets no help from men, and if any part is unfinished at summer's first day, he gets nothing.
The builder agreed. He had one helper: his horse, Svaðilfari. And the horse did the work of many men, hauling stones so fast that by the last three days of winter, the walls were almost done and the gateway unfinished.
The gods panicked and rounded on Loki: this was his idea, he had to fix it. That night, Loki appeared in mare form and lured Svaðilfari away from the building work. The builder, deprived of his horse, couldn't finish. He revealed himself as a mountain giant and was killed by Thor. From the horse Loki had seduced, Sleipnir was eventually born — Odin's eight-legged horse, best of all horses.
The wall of Asgard was almost complete but not quite. The builders and the Norse mythology have a complicated relationship with completion.
The Halls of Asgard
Asgard is not one hall but many. The Norse sources describe a city of divine palaces, each belonging to a different god or serving a specific function.
Valhalla
Odin's great hall, where the Einherjar — the chosen dead warriors — feast and fight until Ragnarök. Its roof is made of shields; its rafters are spears; it has 540 doors, each wide enough for 800 warriors to walk through abreast. Valhalla represents the ideal of the warrior afterlife: eternal feasting and battle, death every day at sparring, resurrection every evening for the feast, preparing for the last battle.
Gládsheimirrn
Odin's council hall, where the gods meet. It contains twelve high seats for the Aesir and Odin's throne Hliðskjálf, from which all the nine worlds can be seen. This is where the business of the cosmos is conducted.
Bilskírnir
Thor's hall, described in the Prose Edda as the greatest hall in all the worlds — even larger than Valhalla. He guards Midgard as much as he guards Asgard, and his hammer Mjolnir is never far from reach.
Sessrumnir
Freyja's hall in her realm Fólkvangr — the field of the people. Freyja chooses half the battle-dead (Odin takes the other half), and they come to Sessrumnir. The Valkyries serve both Valhalla and Fólkvangr, choosing who rises.
Breidablik
Baldr's hall, described as the most beautiful place in Asgard — no impurity could exist there. Its destruction is implied when Baldr is killed and descends to Helheim.
Asgard and Midgard: The Connection
The gods of Asgard are not remote from humanity. They travel to Midgard, interfere in human affairs, have children with humans, and receive sacrifice and prayer from the Norse people. The distinction between the divine and human worlds is one of kind, not of inaccessibility.
Bifrost is not just a bridge for gods. Human souls travel it too — some of them. The dead who go to Valhalla or Fólkvangr pass through or near Bifrost. The worlds are connected and the traffic between them is constant.
The End of Asgard
Asgard falls at Ragnarök. Bifrost shatters under the weight of the fire giants crossing from Muspelheim. The walls the giant almost finished are ultimately insufficient. The halls burn. The gods die. Asgard sinks or is consumed.
But in Voluspá's account, a new world rises from the waters afterward. The surviving gods find each other on the plains of Iðavollr, where Asgard once stood, and discover the gold gaming pieces they once played with scattered in the grass. Whether this is a new Asgard or simply the site of the old one, the implication is of recovery and renewal. The Norse cosmos ends and begins again.

Frequently Asked Questions
How many realms are there in Norse mythology?
Nine, arranged through the branches and roots of Yggdrasil. They include Asgard (gods), Midgard (humans), Jotunheim (giants), Helheim (the dead), Niflheim (ice and mist), Muspelheim (fire), Alfheim (light elves), Svartalfheim (dark elves/dwarves), and Vanaheim (the Vanir gods).
Who guards Asgard?
Heimdall, the Watchman of the Gods, stands on Bifrost and guards the bridge to Asgard. He can see for hundreds of miles in any direction, needs less sleep than a bird, and can hear the grass growing. At Ragnarök, he blows his horn Gjallarhorn to summon the gods to battle.
Is Valhalla the same as Asgard?
No. Valhalla is a specific hall within Asgard — Odin's hall for the chosen warrior dead. Asgard is the entire realm of the Aesir gods, which contains many halls and spaces, of which Valhalla is one (though the most famous).
Can humans visit Asgard?
In the Norse myths, some humans do reach Asgard, particularly heroes and those invited by the gods. Most mortals don't visit Asgard in life — they go to Valhalla or Fólkvangr in death.
