How about getting her a travel guide book to historically rich cities that she is interested in visiting? You could also book a trip to one of her dream destinations, maybe Egypt to see the pyramids, or Peru to hike Machu Picchu! Another idea is to get her a framed map of the world where she can scratch off the places she has visited. If you want a more sentimental gift, you could compile a scrapbook of all the memories you two have made during your travels together.
Or you can get her a star map with an important date you share.
