Himinbjörg

In the poem Grímnismál, Odin (disguised as Grímnir), tortured, starved and thirsty, tells the young Agnar of a number of mythological locations.

The first mention is found in chapter 27, where the enthroned figure of High informs Gangleri that Himinbjörg stands where the burning bridge Bifröst meets heaven.

[5] Later, in chapter 27, High says that Heimdallr lives in Himinbjörg by Bifröst and there guards the bridge from mountain jotnar while sitting at the edge of heaven.

Grimm compares Himinbjörg to the Old Norse common noun himinfiöll for especially high mountains, and the Old High German Himilînberg ('heavenly mountains'), a place haunted by spirits in the Vita sancti Galli, a Himelberc in Liechtenstein and a Himilesberg near Fulda, Germany, besides more examples from Hesse, a Himmelsberg in Västergötland, Sweden and one, "alleged to be Heimdall's", in Halland, Sweden.

Grimm further compares the Old Norse Himinvângar, cognate to Old Saxon hebanwang, hebeneswang, a term for "paradise" and the Old English Heofenfeld ('heavenly field') mentioned by Bede.
