London Arch - Definition

London Arch

London Arch is a natural arch in the Port Campbell National Park, Australia.

The arch is one of the tourist attractions along the Great Ocean Road near Port Campbell in Victoria. It was formed by a gradual process of erosion, and until 1990 formed a complete double-span natural bridge.

The arch closest to the shoreline collapsed unexpectedly on 15 January 1990, leaving two tourists stranded on the outer part: they were rescued by helicopter. No one was injured in the event.

Prior to the collapse, the formation was known as London Bridge because of its similarlity to its namesake.
