Twelve Apostles - on the Great Ocean Road, Victoria, Australia
The Twelve Apostles is the name given to a collection of natural limestone stacks standing just offshore in the Port Campbell National Park, on the Great Ocean Road in Victoria (Australia). 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. There are not actually twelve stacks, but their close proximity to one another has made the site a popular tourist attraction.
The erosion is ongoing: there used to be a feature called 'London Bridge' (because of the likeness to its namesake), a natural arch. Two visitors were trapped on one of the stacks when the 'bridge' collapsed several years ago (they had to be rescued by helicopter). The feature is now called London Arch.
Originally, this site was called the sow and piglets, but the name was changed to a more majestic sounding name.
