There are, in our opinion, three main Celtic symbol for inner strength – the Dara Knot, the Ailm and Crann Bethadh.

The Dara Knot (AKA the Celtic Shield Knot) is the most notable Celtic symbol for strength and it’s intertwined with the ancient oak tree.
The word ‘Dara’ comes from the Gaelic word ‘Doire’, which translates to ‘Oak Tree’. The Celts saw the oak as a symbol of:
- Wisdom: It can grow for over 100 years and they believed it amassed knowledge during this period
- Strength: It stands proudly against storms and attack from both humans and animals
- Immortality: The Celts believed that Celtic Gods were created from the saplings grown from fallen acorns
Many believe that this Celtic strength symbol is meant to depict the intricate root system of an oak. When you look at the symbols above, you’ll get a sense of why.
2. The Ailm

The Ailm is one of the lesser-known Celtic symbols for inner strength and it comes from the ancient Ogham alphabet, which was a form of communication that is still found on stones across Ireland.
Many believe that this symbol represents the pine tree, which was another tree that the Celts revered and often associated with healing and inner peace.
It’s said that the Celts associated the pine, notably the Scots Pine, with healing and cleansing rituals. Pinecones and needles were used to purify and sanctify body and soul as well as the home.
It’s believed that the Celts would hang branches from the pine over where they slept to ward of sickness and to attract strength and vitality.
3. The Celtic Tree of Life

Arguably one of the most impressive Celtic symbol for inner strength, the Celtic Tree of Life is another example of the Celt’s obsession with trees.
They believed in the connection between the earth and the next life and that specific trees held the spirits of their ancestors.
The oak was a symbol of strength, longevity and wisdom, and it was often planted at the center of new communities.
According to legend, the Celts believed that if they were able to cut down their enemy’s tree, it would lead to their victory.
