According to Wodening (2004), The Well of Wyrd (ON: Urðarbrunnr or Urðarbrunni)
springs "at the base of Yggdrasil" (other sources locate it in
Asgard). Wodening affirms that there are two other wells within the Norse
cosmology also at the base of the World Tree: Mímisbrunnr "Mimir's
Well", where Wóden sacrificed an eye to drink of wisdom or abovewhich he
was nailed or bound inverted upon Yggdrasil for nine days and from whence he
retrieved the Runes; and Hvergelmir "the roaring cauldron", the well
that all waters of the Nine Worlds are held to both flow from and to which they
ultimately return. These various wells are often conflated. Bauchatz (1982) affirms that just as The Norn though three are one, so the three Wells of
Wyrd are also one.
In general tradition, The Well of Wyrd, is the wellspring which feeds the taproot, the principal root of Yggdrasil's three. Some traditions, locate The Norn in a hall by the Well where-from they tend the Well and the Tree. In some traditions, The Norn score and incise the Bindrunes of Fate directly onto the living trunk of Yggdrasil from that which they scry in the Well.
Connla's Well - Irish Tradition In Irish mythology (also called the Well of Coelrind, Well of Nechtan, and Well of Segais) is one of a number of otherworldly wells that are variously depicted as "The Well of Wisdom", "The Well of Knowledge" and the source of some of the rivers of Ireland. Much like the Well of Nechtan (and some sources equate the two), the well is the home to the salmon of wisdom, and surrounded with hazel trees, which also signify knowledge and wisdom.
The Purification Well - Isla del Sol - Bolivia
The water from this well is believed by Incas to be sacred and to have purifying effects. You can usually find it in the labyrinth if you watch out for tourists lining up to "purify" themselves.
