The museum features artifacts donated in 1955 from the Bell family's personal museum, located in the Kite House at Beinn Bhreagh. The museum also features memorabilia associated with Bell's experiments, including: the original HD-4 hull of a hydrofoil boat that set the world speed record here in Baddeck of over 70 MPH in 1919; a full-scale replica of that boat; the AEA Silver Dart which in 1909 J.A.D. MacCurdy piloted up into the air over the ice of Baddeck Bay to become the first heavier than air craft to be flown in Canada and possibly the British Empire -- plus many other exhibits and documents from Bell's years of research activities on the transmission of speech and sound by wire and by light, as well as his experiments with kites, planes and high speed boats.  The museum also features displays relating to Bell's work with the deaf and how it led to the invention of the telephone.
