Melville Island (Nova Scotia)

Melville Island is a small peninsula in Nova Scotia, Canada, located in the Northwest Arm of Halifax Harbour, west of Deadman's Island. It is part of the Halifax Regional Municipality.

The site was discovered by Europeans in the 17th century, though it was likely earlier explored by Indigenous peoples. The land is rocky, with thin, acidic soil, but supports a limited woodland habitat. It was initially used for storehouses before being purchased by the British, who built a prisoner-of-war camp to hold captives from the Napoleonic Wars and later the War of 1812. The burial ground for prisoners was on the adjacent Deadman's Island.

Later, Melville Island was used as a receiving depot for Black refugees escaping slavery in the United States, then as a quarantine hospital for immigrants arriving from Europe (particularly Ireland). It briefly served as a recruitment centre for the British Foreign Legion during the Crimean War, and was then sold to the British for use as a military prison. In 1907 the land was granted to the Canadian government, which used it to detain German and Austro-Hungarian nationals during the First World War. During the Second World War, prisoners were sent to McNabs Island instead, and ammunition depots were kept on Melville Island.

The peninsula now houses the clubhouse and marina of the Armdale Yacht Club. Melville Island has been the subject of a number of cultural works, most of which concern its use as a prison.
