In 1488 the Portuguese explorer Batholomeu Dias sailed into Algoa Bay and landed on St Croix island
where his crew celebrated Mass and planted a padrão or stone cross. The island, which is visible from the Port Elizabeth beachfront, is 3.9 km from the nearest land at Hougham Park and rises up to 59m at it's highest point. It is 12 ha in size and is 700 meters long at its longest point and 360m wide at its broadest. There is very little vegetation on this rocky island which is also home to the biggest breeding colony of African Penguins in the world.
