In England, tombstones are sometimes called "ravenstones". Among the Irish Celts, Raven was associated with the Triple Goddess, the Morrigan, who took the shape of Raven over battlefields as Chooser of the Slain. She was a protector of warriors, such as Chuhulian and Fionn MacCual. Raven is also the totem of the pan-Celtic Sorceress/Goddess Morgan le Fay, who was also called the Queen of Faeries. In some tales, she is Queen of the Dubh Sidhe, or Dark Faeries, who were a race of tricksters who often took the form of ravens. Irish and Scots Bean Sidhes (Banshees) could take the shape of ravens as they cried above a roof, an omen of death in the household below.

Tha gliocas an ceann an fhitich or Fice ceann na fhitich are Scots Gaelic proverbs meaning "There is wisdom in a raven's head." it is also said "To have a raven's knowledge" is an Irish proverb meaning to have a seer's supernatural powers. Raven is considered one of the oldest and wisest of animals.

Also a bird of wisdom and prophecy, Raven was the totem of the Welsh God, Bran the Blessed, the giant protector of the Britain, the Isle of the Mighty. After the battle with Ireland, Bran was decapitated, and his head became an oracle. Eventually Bran asked to have his head buried in what is now Tower Hill in London to protect Britain from invasion. Bran's Ravens are kept there to this day, as protection against invasion. During World War II, Tower Hill was bombed, and the ravens were lost. Winston Churchill, knowing full well the ancient legends, ordered the immediate replacement of ravens, and they were brought to Tower Hill from Celtic lands - the Welsh hills and Scottish Highlands. Raven was the favorite bird of the solar deity, Lugh (Irish/Scots), or Lludd (Welsh) the Celtic God of Arts and Crafts. Lugh was said to have two ravens to attend on all the His needs (similar to Odin and his ravens). Many Celtic tribes and clans descend from animals. An ancient clan called the Brannovices, the Raven Folk, once existed in Britain. To this day, the Glengarry MacDonalds of Scotland have a raven on their heraldic arms, and their war cry is Creagan-an Fhithich - Raven's Rock, a landmark on their ancestral lands. The Scottish Goddess of winter, The Cailleach, sometimes appears as a raven and old Scottish rumours said that a touch from her brings death. Giving a child his first drink from the skull of a raven will give the child powers of prophecy and wisdom in the Hebrides.
