The Heart's Content Cable Station consists of an 1875 office building and a 1918 extension.In July 1866, the first permanent telegraph cable connecting Europe and North America was hauled ashore at Heart's Content. It took nine years and several unsuccessful attempts.
The cable station opened the world to the province and operated into the 1960s.
The cable station remained part of the Western Union Inc.'s international cable system until the facility was closed after trans-ocean telephone cable and satellite communication made its technology obsolete.
