Alexander Graham Bell National Historic Site, Heritage museum in Baddeck, Canada

The Alexander Graham Bell National Historic Site in Baddeck is a museum housing original artifacts from Bell's laboratory, personal papers, and experimental devices. The collection includes materials from the Bell family's private holdings kept at their residence, Kite House.

The site was designated a National Historic Site in 1952, and its museum building was designed by government architect O. Howard Leicester with the firm Wood, Blachford, Ship. The exhibits grew from artifacts donated in 1955 by the Bell family's personal museum in the Kite House at Beinn Bhreagh. The collection covers Bell's experimental years in Baddeck, from speech transmission to kites, planes and fast boats.

The museum holds the Bell family's personal collection, donated in 1955 from their museum in the Kite House at Beinn Bhreagh. Displays trace how Bell's teaching of deaf students led him to the telephone, alongside his later work on kites, planes and fast boats at Baddeck.

The museum stands in Baddeck on Cape Breton Island, overlooking the Bras d'Or Lakes. A rooftop observation deck looks across the bay toward Beinn Bhreagh, Bell's estate, which is privately owned and closed to the public. The building has a stone base, a band of glass windows and doors, and a tall triangular gable of dark panes in wood framing.

The museum displays the original hull of the HD-4 hydrofoil boat, which set a speed record of 112 kilometers per hour in 1919. This vessel was among Bell's many experimental constructions that showcased his creative problem-solving approach.
