Signal Hill National Historic Site

Signal Hill rises steeply above the narrows of St. John's Harbour and served as the strategic point where Guglielmo Marconi received the first transatlantic wireless signal in 1901. Cabot Tower, a castellated stone structure at the summit, was built in 1897 to commemorate the four-hundredth anniversary of John Cabot's landfall. The hill commands panoramic views of the city, the harbour, and the open North Atlantic.
