In keeping with John Hays Hammond, Jr’s original vision for his seaside castle-home to serve as a museum offering the Gloucester community access to ancient works of architectural art, Hammond Castle Museum will offer Gloucester residents free, self-guided tours each Tuesday throughout the regular season which runs through the end of October. 

Have You Visited Hammond Castle Museum Lately?
Guests may explore the breathtaking building and grounds of Hammond Castle Museum and take guided tours offering new insight into the inventor that was one of the North Shore’s most dynamic residents. This year the museum will offer new exhibits. The Spring/Summer rotating exhibit will feature John Hays Hammond Jr's explorations throughout Europe, the Caribbean, and Canada. In the Summer/Fall, the Museum will feature a temporary exhibit on Hammond’s family with a focus on John Hays Hammond, Sr. There will also be an exhibit on the staff members of the Hammond’s household.

Self-guided tours require registration which may be made in advance of your visit or upon arrival at the Museum. Self-guided tours are available from 10 am to 3pm, to allow for enough time to adequately tour the museum which closes at 4pm. Proof of residency for all reservations is required upon check in at the Museum.  Reservations may be made at  www.hammondcastle.org.
