One idea for a birthday gift for your grandma who likes medieval history could be a subscription to a history magazine that specializes in medieval history. Another idea could be a book about a specific aspect of medieval history that she might enjoy, such as a biography of a famous medieval figure or a book about the architecture of medieval castles. Depending on where you live, you could also take her to a medieval festival or fair in your area as a fun outing. If she's interested in crafts, you could get her some medieval-style tapestries or a calligraphy set to try.
Or you can get her a star map with the date when she was born.
