Parc national de Port Campbell, Exhibition house, Twelve Apostles

The Twelve Apostles, like the other rock formations of the Port Campbell National Park, have been gouged away from the towering limestone cliffs over thousands of years. The cliffs' foundations were laid down some 10 to 25 million years ago at a time when this area was covered by an inland sea. The exhibition house is located next to the Great Ocean Road, about 250km from Melbourne, Australia.
