Urðarbrunnr
The holy well beneath Yggdrasil where the Norns live and the gods hold their daily court; its white water keeps the world-tree green.
Urðarbrunnr, the well of Urðr, lies under the world-tree Yggdrasil. It is where fate is made and where the gods sit in judgement.
In Völuspá the tree stands "green by Urth's well", wet with a white water from which the dews fall into the dales Völuspá 19. From there come three maidens "mighty in wisdom": Urðr, Verðandi and Skuld, who carve on wood, make laws and "set the fates" of the sons of men Völuspá 20. The well is named for the first of them. Hávamál uses it as a place of wisdom: the speaker says "By the wells of Urth I was, / I saw and was silent", before passing on what he heard Hávamál 111.
Snorri gives the well a position and a function. One root of the ash "stands in heaven", and under it is the well, "very holy", where the gods hold their court; each day they ride to it over Bifröst Gylfaginning 15. A fair hall stands by the well, and from it come the Norns who decide the length of men's lives Gylfaginning 15. Every day they take water and the white clay around the well and sprinkle the tree so that its limbs do not rot. The water is so holy that everything in it turns white "as the film which lies within the egg-shell"; two swans feed on it, ancestors of all swans; and the dew that falls from the tree is the honey-dew that bees feed on Gylfaginning 16.
Snorri's placement is his own synthesis. Grímnismál, which he otherwise follows closely, puts Hel, the frost-giants and mankind under the three roots and does not mention the well Grímnismál 31. The other wells of the tree are Mímir's well and Hvergelmir.

Thence come the dews that fall in the dales, Green by Urth's well does it ever grow.
Thence come the maidens mighty in wisdom, Three from the dwelling down 'neath the tree
By the wells of Urth I was, I saw and was silent
under that root is the well which is very holy, that is called the Well of Urdr; there the gods hold their tribunal.
these Norns who dwell by the Well of Urdr take water of the well every day, and with it that clay which lies about the well, and sprinkle it over the Ash
Where the sources disagree or fall silent
- Grímnismál lists the three realms under Yggdrasil's roots (Hel, frost-giants, men) without mentioning Urðr's well; Snorri places it under a heavenly root. The poems never say which root it lies under.
- Hávamál's plural 'wells of Urth' may refer to the same place or be a poetic variation.
In modern culture
Not from the medieval sources.
The well of Urd is a frequent image in modern pagan practice and in fantasy writing, where it often becomes a well of fate or time. These uses build on Snorri's description.
