Triple Island Lightstation

Triple Island Lightstation, on a tiny exposed islet in British Columbia, is a staffed concrete lighthouse completed in 1920 after four years of construction. Its 23-metre tower is attached to a rectangular building housing keepers’ quarters and machinery, while a helipad now occupies much of the remaining site. Still operated by Canadian Coast Guard personnel on 28-day rotations, it continues to serve as a working aid to navigation. The station also supported science: from 1939 to 1970, staff gathered daily coastal water temperature and salinity data for the British Columbia Shore Station Oceanographic Program. Its enduring significance was recognized in 1974 with designation as a National Historic Site of Canada.
