Asgard

Asgard, Old Norse Ásgarðr, 'enclosure of the gods', is the home of the Aesir in Norse mythology, including Odin and Thor. It is mentioned in the Eddic poems Hymiskvida and Thrymskvida and described most fully by the Icelandic writer Snorri Sturluson in his Prose Edda, about 1220.

In Snorri's Gylfaginning the gods build Asgard in the middle of the world, and the bridge Bifrost links it to Midgard, the human world. Odin's hall Valhalla stands within it. Asgard plays a role similar to Mount Olympus in Greek myth.

Snorri, a Christian writer, also offered a 'historical' version. His prologue identifies Asgard with Troy, and his Ynglinga saga places it in Asia, east of the river Tanais, with the Aesir as human rulers later worshipped as gods. These versions show how medieval scholars tried to fit the old gods into Christian and classical history.
