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.
New this season, the Museum features four temporary exhibits that explore John Hays Hammond Jr. as both an individual and a scientific innovator.

Beginning September 10th and running through the end of the 2025 season on January 4th, Leysath will showcase” Hammond in Italy: The Love Affair Between the Hammonds & Italian Culture.”Additionally, the Inventions Exhibit Room will highlight Hammond’s groundbreaking Videotape Technology during the spring and summer months, followed by Hammond’s ahead-of-their-time Advertising Signs in the fall and early winter.
