London Arch

London Arch (English London Arch, formerly London Bridge, Eng. London Bridge ) is a natural rock arch in the Port Campbell National Park in Australia, near the Great Ocean Road.

The bow of a Campbell - limestone, which originated in the Tertiary, is one of the many tourist attractions along the Great Ocean Road near Port Campbell in Victoria. The rock has been eroded by natural erosion, so that it formed a double arch until 1990. This formation was enough to the coast, and was then called the London Bridge because of their appearance. Such arcs are formed when rock formations are exposed from different resistant rocks of the erosion, so that some areas of weather more quickly than others and can be washed away. The slowly eroding areas then form the arches or the observed structures. However, these rocks are of course subject to erosion, so that it can be expected that they break down sooner or later in themselves or be removed. The formations consist, as seen in geological time, only for a short time.

The inner bow - the bridge connection to the mainland - crashed on January 15, 1990 unexpectedly. Two tourists who were at the time of the collapse on the rock had to be rescued by helicopter. The formation was renamed after the event in London Arch.

London Arch is one of a series watchable rock formations along this stretch of the Australian coastline. Additional points of interest include Pudding Basin rock, Loch Ard Gorge, Iceland Archway, The Razorback, the uninhabited Muttonbird Iceland, Thunder Cave, The Blowhole, Elephant Rock, Bakers Oven, The Grotto and the Twelve Apostles.

In June 2009, collapsed, another rock arch of this coast, the nearby Iceland Archway.
