London Arch

London Arch is a natural limestone arch located in Port Campbell National Park along the Great Ocean Road in Victoria, Australia, about 6 kilometres west of Port Campbell. Formerly known as London Bridge, it originally formed a double-span bridge connected to the mainland until part collapsed in 1990. The offshore arch is a prominent coastal landmark within the Twelve Apostles marine and coastal landscape, noted for its distinctive shape, dramatic cliffs and ocean views.

Visitors can expect an offshore natural limestone arch viewed from two sealed lookouts above dramatic coastal cliffs. The upper lookout is close to the car park and the lower lookout is accessed via steps, both offering panoramic views of the arch, ocean and rugged coastline. The site includes interpretive signs, open cliff-top surroundings and opportunities for sightseeing and photography. There is no beach access at the arch itself.

Formed over millions of years by coastal erosion of limestone cliffs. Known as London Bridge due to its resemblance to the bridge in London, it was a double-span natural bridge connected to the mainland until the inner span collapsed unexpectedly on 15 January 1990, stranding two visitors on the outer arch who were later rescued by helicopter. Since then it has been known as London Arch.

Located within Port Campbell National Park on the traditional Country of the Eastern Maar people, the coastline is part of a culturally significant landscape valued for its natural heritage and long-standing connection to Aboriginal Country.
