The Needles are a row of three stacks of chalk that rise about 100ft out of the sea off the western extremity of the Isle of Wight in the English Channel, United Kingdom, close to Alum Bay and Scratchell's Bay, and part of Totland, the westernmost civil parish of the Isle of Wight. The Needles Lighthouse stands at the outer, western end of the formation. Built in 1859, it has been automated since 1994. The waters and adjoining seabed form part of the Needles Marine Conservation Zone and the Needles along with the shore and heath above are part of the Headon Warren and West High Down Site of Special Scientific Interest
Situated within The Needles is the world famous Marconi Monument, which marks the precise location where Marconi undertook his pioneering work at the end of the 19th Century, which led to radio and all telecommunications as we know it today.
