hammond castle museum photoCome explore Hammond Castle Museum on a guided or self guided tour of Cape Ann's most unique treasures! You'll also enjoy the beauty of the castle grounds including our iconic arches, drawbridge and bell tower, and an excellent view of the Atlantic shore line.

John Hays Hammond Jr., known as “The Father of Radio Control,” was one of America’s most prolific inventors and a protégé of Guglielmo Marconi, Nikola Tesla, Thomas Edison, and Alexander Graham Bell.

Built from 1926 through 1929, and incorporated as a museum in 1930, the Castle’s architectural style is a mix of a medieval castle, French chateau, and a Gothic cathedral.

It was custom built to encompass Hammond’s private residence, laboratory, and museum quality collection of architectural elements such as the facades of medieval shops and doorways from chateaus.

Also on display is Hammond’s extensive list of patents, his work with radio control, and his work on guided torpedoes for the military.

Hammond Castle Museum is a 501(c)(3) non-profit organization and is listed on the National Register of Historic Places.

80 Hesperus Avenue, Gloucester, MA, 01930 map
Phone: (978) 283-7673


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 castle, and turn onto Hesperus Avenue. The castle 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.


A mysterious castle, Grade 2 Student
It is really, really mysterious because it was made a long time ago. I highly recommend it because it was adventurous. It has lots of doors, and some mystery doors, and paths in the gardens, and stairs going down to see the ocean. And it has a private graveyard! Don't go on a Monday, because it's closed!
A hidden jewel, Grade 4 Student
Hammond Castle was great but wish that is was open Mondays. The outside of the castle is great with fantastic views. They have a quarter machine telescope and the view of the ocean is beautiful. I felt like I was a princess at a beautiful castle. The grounds are beautiful and there is also a private area for his headstone. I enjoyed walking the pathways through the elegant garden. I had lots of fun at Hammond Castle.
