Alexander Graham Bell National Historic Site is a 10-hectare (25-acre) property in Baddeck, Cape Breton, Nova Scotia, Canada, overlooking the Bras d'Or Lakes.

The site features artifacts donated in 1955 from the Bell family's personal museum, located in the Kite House at Beinn Bhreagh.

MacCurdy piloted up into the air over the ice of Baddeck Bay to become the first controlled heavier-than-air craft to be flown in 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.

In addition to its displays, the museum features an observation deck on the roof of the building offering a view of Bell's Beinn Bhreagh estate, across the bay.
