A notable landmark in colonial times, the islets are less well known as the Three Sisters Islands and Three Sisters Island. Bridges have been proposed for the Three Sisters several times, most recently in the 1960s, when the Three Sisters Bridge proposal led to a decade of protests and ultimately, its cancellation.
