Katie Holten’s Irish Tree Alphabet allows us to write in Irish Trees. Her art explores language and the environment to highlight the importance of our words and the stories that we tell.


Katie has made drawings of trees, existing natives as well as non-native trees that are now calling Ireland home due to the changing climate. Each tree replaces a letter in the Latin alphabet; A = Ailm (Scots Pine), B = Beith (Birch), C = Coll (Hazel), etc. The result is a new Irish Tree Alphabet and font called Irish Trees. 


The project finds its roots in the Ogham alphabet, a medieval alphabet used primarily to write the early Irish language. Ogham's characters or letters were called feda "trees" or nin "forking branches" due to their shape.

For National Tree Week
