Cabot Tower, Gothic Revival tower on Signal Hill, St. John's, Canada
Cabot Tower is a sandstone structure on Signal Hill composed of a two-story square base with an octagonal three-story tower on its southeast corner. The interior holds exhibits exploring maritime radio communication and wireless technology from its operational years.
Construction began in 1898 to mark the 400th anniversary of John Cabot's landing and Queen Victoria's Diamond Jubilee, and the tower was completed in 1900. It was the last in a line of signalling blockhouses on Signal Hill, used for flag signalling until 1958. A Marconi station operated on the second floor from 1933 to 1960.
The tower served as a navigation landmark for sailors approaching the harbor and remains connected to the port's maritime identity. Today it represents the city's link to seafaring traditions and communication history.
Visitors can climb the tower's interior stairs to reach viewing areas overlooking the harbor and Atlantic Ocean while exploring exhibits on radio history. The location sits atop a hill, so plan for some walking to reach the entrance.
The tower received the first transatlantic wireless voice transmission in 1920, a milestone in communication technology. This achievement positioned St. John's as a key hub in early wireless development.
