A permanent electrical communications link between the old world and the new was initiated at this site with the landing of a transatlantic cable on July 27, 1866. This achievement altered for all time personal, commercial, and political relations between peoples on the two sides of the ocean. Five more cables between Heart's Content and Valentia, Ireland were completed between 1866 and 1894. This station continued in operation until 1965. IEEE Canada maintains a web site about this Milestone.
