How about a Celtic-inspired piece of jewelry? You could consider a Celtic knot pendant or a ring with a similar design. You could also consider getting him a book on Celtic mythology or history, or a trip to a place with a strong Celtic cultural influence, like Ireland, Scotland or Wales. Another idea could be to get him a personalized Celtic-inspired item, like a flask, a decanter or a mug. Lastly, you could write him a heartfelt letter or poem with a Celtic-inspired design on the paper or envelope.
Or you can get him a star map with the date of your anniversary.
