With its summit 167 metres above sea level, Signal Hill offers a commanding view of the Atlantic Ocean, St. John’s, and the Narrows, a channel through which all ships must pass when entering St. John’s Harbour. This site was important for communications and defence. Its fortifications defended St. John’s harbour for centuries and it was at the summit of Signal Hill on December 12th, 1901 that Guglielmo Marconi received the first transatlantic wireless transmission ushering in the era of wireless communications.
