Hammond Castle Museum

About Us

Step inside the breathtaking home of one of the most prolific inventors of the 20th century, John Hays Hammond, Jr.

Hammond Castle Museum is a dynamic STEAM museum, blending its historical significance as both a historic house museum and a lapidarium. Inside, you’ll not only discover ancient, medieval, and Renaissance architectural elements and artifacts—including stone archways, sarcophagi, grave markers, and an extraordinary collection of stone and marble works—but you’ll also find a vibrant museum offering fresh educational and cultural arts programming. Visitors can explore items from the archival collection that have not been publicly seen in generations, along with newly curated content and the most up-to-date information on the provenance of many pieces in our collection. In addition, the Museum offers prearranged tour opportunities for school and tour groups.

Listed on the National Register of Historic Places, and a repeated Reader’s Choice Best of North Shore winner by Northshore Magazine and a Trip Advisor Traveler’s Choice award recipient for the last three consecutive years, you can trust that your visit will be an unforgettable experience.
