How about gifting your boyfriend a replica of a medieval sword or a book on medieval history? You could also consider taking him on a romantic getaway to a medieval-inspired castle so you can both immerse yourselves in the history he loves. Alternatively, you could plan and host a medieval-themed evening, complete with period-appropriate entertainment, costumes, and food.
Or you can get him a star map with the date of your anniversary.
