Cabot Tower was built in 1897 to commemorate the 400th anniversary of John Cabot's discovery of Newfoundland.
It is located on top of Signal Hill overlooking the city of St. John's, Newfoundland and Labrador.
In 1901, Guglielmo Marconi received the first trans-Atlantic wireless message at a position near
the tower, the letter "S" in Morse Code sent from Poldhu, Cornwall, United Kingdom.
