What is the name of the well that contains the eye of Odin?

The well containing Odin’s eye is Mímisbrunnr, the “wellspring of Mímir.” Its water holds wisdom, and Odin surrendered one of his eyes as a pledge so that he could drink from it.

Mímisbrunnr lies beneath one of the roots of Yggdrasil, the cosmic tree connecting the worlds. The well is associated with Mímir, a profoundly wise being who drinks from it each morning. In the Prose Edda, Mímir’s knowledge is directly linked to the well’s water and to the sacrifice required for Odin’s drink.

The eye is not merely lost in battle or destroyed; Odin deliberately places it at the well as collateral for access to its wisdom. This bargain explains why Odin is depicted as physically incomplete but exceptionally knowledgeable. The sacrifice is one of the clearest examples of wisdom carrying a personal cost in Norse mythology.

Mímisbrunnr is often confused with the other famous wells beneath Yggdrasil. Hvergelmir is associated with Niflheim and the origins of rivers, while Urðarbrunnr is linked with the Norns.
