The foundation stone of the graving dock at the Williamstown Naval Dockyard, VIC, was laid by HRH Prince Alfred, KG, Duke of Edinburgh, who arrived in Port Phillip in the Royal Navy’s steam frigate HMS GALATEA, having sailed from Plymouth on 24 January 1867 on a round the world voyage, visiting South America, the Cape, Australia, China, India, and Japan. The voyage was interrupted on 12 March 1868 in Sydney by a Fenian assassination attempt.
