Cabot Tower stands on Signal Hill above St Johns in Newfoundland. The tower was built in 1897 to commemorate the 400th anniversary of John Cabot’s discovery of Newfoundland and later became historic in it’s own right when it was used as a Marconi wireless station. It was on Signal Hill that the first transatlantic signal was received in 1901 and the first wireless transatlantic transmission of a human voice was received here in 1920. The wireless station operated until 1958 and is now part of a Canadian National Historic Park and is still used for transmissions by the local amateur radio society.
