How about a personalized map print of all the cultural landmarks he has visited? You can easily find these online, with the option to customize the design and include personalized messages. Another idea could be a travel guidebook or book about cultural landmarks around the world, so he can plan future trips and learn about new places. If you're looking for something more sentimental, you could also create a photo album of your travels together, with captions and stories from your experiences.
Or you can get him a star map with the date of your first kiss.
