Adelaide's Underwater Heritage Trail explores four shipwrecks located in Gulf St Vincent - the Grecian, Zanoni, Star of Greece and Norma.
These wrecks represent a variety of vessels associated with trade and development in South Australia during the nineteenth and early twentieth century's and spans the period of British shipbuilding from 1841 to 1893.
The remains demonstrate the four major types of materials used in sailing vessel construction during that era - wood, composite (wood and iron), iron and steel.
This trail extends from the Star of Greece, off Port Willunga, to the Zanoni, about 15 kilometres south east of Ardrossan, and includes a brochure and four underwater plaques placed adjacent to each wreck.
