How about making a donation in his name to a nonprofit organization that focuses on heritage preservation, such as the National Trust for Historic Preservation? Another idea would be to plan a weekend getaway to a historic location, such as a bed and breakfast in a charming historic district, or visiting a nearby historical site, like a museum or old battlefield. You could even book a guided tour focused solely on the history and heritage of the area. If your husband is interested in genealogy, consider gifting him a DNA testing kit or a subscription to a family history website to help him learn more about his own roots and history.
Or you can get him a star map with the date of your anniversary.
