Thousands of years ago, Old Harry and The Needles (another chalk rock formation) on the Isle of Wight were linked by a line of chalk hills that eroded away during the last ice age. On a clear day you can see The Needles from Studland Bay.

There are a number of theories about where Old Harry got its name. It is reputedly named after either a famous local pirate (Harry Paye) or the devil. The top of the cliff nearby is known as Old Nick’s Ground which is another name for the devil.
