London Bridge (Victoria)

London Bridge is an offshore natural arch in the Port Campbell National Park, Australia. The arch is a significant tourist attraction along the Great Ocean Road near Port Campbell in Victoria. The stack was formed by a gradual process of erosion, and until 1990 formed a complete double-span natural bridge. The span closer to the shoreline, sparked comparisons with this nursery rhyme and collapsed unexpectedly on 15 January 1990, leaving two tourists stranded on the outer span before being rescued by police helicopter. No one was injured in the event.
