One idea would be to get your grandson a scratch-off world map where he can scratch off countries as he travels to them. It would be a fun and interactive way for him to keep track of all the cultural landmarks he visits.
Another idea could be a travel guidebook featuring cultural landmarks around the world that he hasn't visited yet. He would love planning out his future trips and discovering new places to explore.
If he's into photography, consider getting him a high-quality camera or a new lens to capture all the cultural landmarks he visits.
Lastly, a membership to a travel rewards program or a hotel loyalty program could also make a great gift. It would allow him to earn points for his travels that he can use towards future trips and experiences.
Or you can get him a star map with an important date you share.
