Sandcastles are part of many people's childhood. A sandy beach, a bucket and a spade and damp sand are all you need and perhaps the desire to become an architect, engineer or builder. This sandcastle competition is open to six to eleven year olds and sponsored by the Daily Mail newspaper and overzealous parents and relatives are kept behind the cordon at a safe distance. By the 1970s the Californians had taken sandcastle building to the whole new art form of the sand sculpture.
