Hammond Castle Museum was the home and laboratory of John Hays Hammond Jr., one of America’s most prolific inventors and the “Father of Radio Control.” Built between 1926 and 1929 and incorporated as a museum in 1930, the Museum blends medieval, Gothic, and French village architectural styles, offering visitors a unique historical and cultural experience in Massachusetts.
Today, Hammond Castle Museum is a dynamic, STEAM-inspired museum blending historical significance with rich collections and contemporary educational programming. Inside, visitors can explore ancient, medieval, and Renaissance architectural elements, including stone archways, sarcophagi, grave markers, an extraordinary lapidary collection of stone and marble works. Newly curated content and archival items not publicly seen in generations provide fresh insight into the provenance and stories behind the collection.
Hammond Castle Museum is listed on the National Register of Historic Places.
2026 Temporary Exhibits at Hammond Castle Museum
This year, the Museum presents four temporary exhibits. Access to the exhibitions is included with your general admission:
- Eric Pape Fine Art Exhibition (April 3 – April 26, 2026)
Featuring over 100 rare pen and ink illustrations by Golden Age artist Eric Pape, this immersive exhibit includes original works created for classic literary titles such as The Arabian Nights, Fairy Tales by Hans Christian Andersen, Rip Van Winkle, The Legend of Sleepy Hollow, Notre-Dame de Paris by Victor Hugo, works by William Shakespeare, and The Heart of a Child by Gertrude Slaughter. Most of these pieces have not been publicly exhibited since Pape’s death in 1938.
- Inside the Faraday Cage: The Science of Things That Aren’t So (May 2 – September 7, 2026)
Is a temporary exhibition exploring John Hays Hammond Jr.’s 1950s experiments with extrasensory perception, consciousness, and communication with spirits. Visitors can step into an interactive, life-size representation of a Faraday cage, take photos with life-size cutouts of Hammond and psychic medium Eileen Garrett, and experience the sensation of being inside a Faraday cage while viewing artifacts from the 1951 experiments.
- Brave Too Much: The Legend of John Coffee Hays (May 2 – September 7, 2026)
The Hays in John Hays Hammond Jr. is a tribute to his great-uncle, Colonel John Coffee Hays. Called “Captain Jack” by his friends and “Devil Jack” by his enemies, this lawman and soldier had a life and career so storied and successful that it has passed into legend. This is a rare case when legend is inseparable from documented history. From Tennessee to Texas to Mexico to California, Jack Hays cantered along a trail of adventure and glory rivaled by few in U.S. history. Yet this Texas Ranger-turned-military commander-turned-Sheriff remained humble; our exhibit is not bound by such restraint.
- Deck the Halls Holiday Celebration, A Museum-Wide Installation (November 21 –January 3, 2027)
For the 2026 holiday season, Deck the Halls transforms Hammond Castle Museum into an immersive winter wonderland where historic rooms are lavishly dressed with lush greenery, sparkling lights, White Birch and Christmas trees, elegant bows, and festive wreaths that celebrate the season’s romance and grandeur.
