For your grandson who is fond of Celtic culture, you might consider the following gift ideas:
1. A book on Celtic mythology or folklore, like "The Book of Celtic Myths" by Adams Media, which features adventurous tales from Ireland, Scotland, and Wales.
2. A traditional Celtic instrument, like a tin whistle or bodhran drum. This can help him create his own Celtic music and immerse himself in the culture.
3. A piece of Celtic jewelry, such as a Celtic knot ring or pendant, that can be passed down to future generations to keep the culture alive.
4. A trip to a Celtic festival or event. This will give your grandson the opportunity to experience the culture firsthand and maybe even try traditional Celtic food and music.
5. A DVD or Netflix subscription to a popular series about Celtic history, like "Outlander," " Vikings," or "The Last Kingdom."
