The Twelve Apostles are a collection of natural limestone stacks standing just off shore in the Port Campbell National Park, on the Great Ocean Road in Victoria, Australia. Their 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 left.
The stacks have been formed by erosion, and are varying heights and thicknesses. A number have fallen over entirely as waves continually erode their bases. A 50-metre tall Apostle collapsed on July 3, 2005, leaving eight.
