Alexander, who succeeded Paul in March 1801, appointed Cameron the chief architect of the Russian Admiralty During this brief (1802–1805) employment Cameron designed the Naval Hospital in Oranienbaum and two unrealized drafts for the Naval Cathedral in Kronstadt. He also worked in Pavlovsk, restoring the palace after a fire. In 1805 Cameron finally retired; his tenure at the Admiralty passed to Andreyan Zakharov. Lukomsky noted that Cameron, who once executed Catherine's soaring dreams, was hardly interested in building barracks and repairing gateways.
