The landmark features a row of three stacks of chalk that rise almost 100ft (30.4m) out of the sea. The lighthouse at the end was built by Trinity House in 1859, with engineers using dynamite to create a platform for it on one of the chalk stacks

These photogenic chalk formations off the coast of Dorset are collectively known as Old Harry Rocks, but the name Old Harry actually refers to the single stack of chalk standing furthest out to sea. Until 1896 there was another stack known as Old Harry’s Wife, but erosion caused her to tumble into the sea, leaving a mere stump. The sea stacks were originally part of the chalk ridgeline that runs across the south coast all the way to the Needles on the Isle of Wight

The London Arch is an offshore natural arch in the Port Campbell National Park in southeast Australia. The rock formation was previously known as the London Bridge as the arch was connected to the mainland via another arch, making it look like its manmade British counterpart. However, the connecting arch collapsed in 1990 and the landmark’s name was adapted. Before it collapsed, visitors could walk right to the end of the rock bridge
