Hammond Castle Museum Tours
Visit the breathtaking home of one of the most prolific American inventors of the 20th century!
The Hammond Castle Museum is a dynamic STEM museum offering guided and self guided tours, temporary exhibits, cultural events and educational programming. Candlelight and spiritualism tours, concerts, movies and more take place throughout the year.
Built in the late 1920s as the home and laboratory of inventor, John Hays Hammond, Jr, the museumís architectural style is mixture of a medieval castle, a Gothic cathedral, and a Renaissance-era French village set amongst Roman ruins.
On permanent display are exhibits relating to Hammond's many patents, including his work with radio control, television, military, and nautical inventions.
Throughout the 2023 season guests can enjoy a completely updated Invention Room, showcasing exciting new perspectives on Hammondís work as a scientist, inventor and engineer.
This season visitors will enjoy a brand-new set of rotating exhibits including an interactive presentation that uses an AI-generated, animated, holographic projection of Hammond, who speaks to visitors about his scientific career which will be on display starting in May and running through the end of August!
If you prefer to take a self-guided tour, you may explore the museum and grounds at your own pace and enjoy the same access to the various exhibit rooms as guided-tour guests. Self-Guided Tour tickets are only available for purchase on-site in the Museum Shop.
The last opportunity to begin a self-guided tour is at 3:15pm to allow for time to explore the museum which closes promptly at 4:00 pm.

How to reach the Museum:
Take I-95 North out of Boston to Exit 45, then route 128 North to Exit 14. Turn right onto Route 133 to the very end of that highway, and with the ocean directly in front of you turn right onto Route 127. Approximately 3/4 of a mile from that intersection the road will begin to narrow. Look for a blue and white sign on your left for the Museum, and turn onto Hesperus Avenue. The museum is just a few blocks down Hesperus Avenue on your left. Park in the lot off the street, and take the walkway and stairs down to the entrance.
