St. Paul Island () is a small uninhabited island located approximately northeast of Cape North on Cape Breton Island and southwest of Cape Ray on Newfoundland; it is along the boundary between the Gulf of St. Lawrence and the Cabot Strait. Overview An extension of the Appalachian Mountains and the Cape Breton Highlands, the highest point on St. Paul Island is 147 m (485 feet) atop "Croggan Mountain". At the time the first Loyalist settlers arrived in Victoria County, St. Paul was known as , meaning "A Round Island" in Miꞌkmaq. St. Paul Island is approximately three miles long by one mile wide at its widest point. It is formed of granite and is extremely rugged with its shores being completely encircled by rockface cliffs. It is split by a narrow channel that fills with sea water. The only land mammals inhabiting the island are originally domesticated rabbits, which were set loose after the lifesaving station was established in the late 1800s (the ramp and massive rowboat for 10 men were still there in 1950/51 as well as an enormous house including a dam forming a fresh water reservoir also used by the radio range station operators and families up to the 1950s). The remains of a WWII RCAF radar station were also still there facing the landing area in 1950/51. It is also inhabited by numerous seabirds. There are also two small lakes in the interior stocked with trout. Its ecosystem is considered fragile and due to the danger posed by visiting the island, visits must be cleared beforehand with the Canadian Coast Guard which administers the island on behalf of its owner, the Government of Canada. The island is nicknamed the "Graveyard of the Gulf" (of St. Lawrence) as it is fog-bound throughout much of the navigation season and posed a significant hazard during the Age of Sail. There is no evidence of its use by indigenous people and it is believed to have been discovered by John Cabot. A lighthouse was first established on the island in 1839. This lighthouse burned down in 1916. It was replaced by a cast iron cylindrical lighthouse in 1917. This was in turn replaced by an automated system in 1962. With the light station now automated using solar power, the island sees few visitors, aside from Canadian Coast Guard helicopters on maintenance trips. The island used to host a Marconi wireless
