Tristan da Cunha formerly used the coat of arms of Saint Helena
The arms consist of a shield featuring four albatrosses in a blue-and-white mirror image design. The central diamond-shaped charge is based on a charge from the arms of the da Cunha family to which Admiral Tristão da Cunha belonged, after whom the island is named: "cunha" in Portuguese means "wedge", and blue wedges feature in the da Cunha arms as a canting charge. The two supporters are Tristan rock lobsters, which are found in the waters surrounding the island. The crest features a naval crown and a Tristan da Cunha longboat.
The motto is “Our faith is our strength”.
