Signal Hill National Historic Site - Parks Canada

St. John’s most popular landmark, Signal Hill, recalls the town’s historic past and communications triumph, as well as offering coastal hikes and colourful performances, against sweeping views overlooking the Atlantic. Signal Hill was the site of St. John’s harbour defences from the 17th century to the Second World War and where Guglielmo Marconi received the world’s first transatlantic wireless signal in 1901.
