The Twelve Apostles

The Twelve Apostles in Victoria are a collection of natural limestone stacks standing off shore in the Port Campbell National Park, on the Great Ocean Road in Victoria, Australia. Their close proximity to one another has made the site a popular tourist attraction. Originally the site was called the Sow and Piglets. The name was changed in the 1950s to the more majestic "The Twelve Apostles" to lure more visitors, even though there were only nine stacks.

The stacks have been formed by erosion, and are varying heights and thicknesses. A number have fallen over entirely as their bases are being continually eroded by the force of the waves. A 50-metre tall Apostle collapsed on July 3, 2005, leaving eight. The previous well known feature in Port Campbell National Park to succumb to erosion was the 'London Bridge.' Two visitors were trapped when a natural arch collapsed - the people were rescued by helicopter a few hours later. The island of rock has since been called 'London Arch.'The rate of erosion at the base of the limestone pillars is approximately 2 cm per year.
