This parapet does not form part of the wall, but is detached from it, being built out about two feet and supported by a sort of scaffolding brace of masonry.

This leaves a space between the battlement and the wall, which in olden times, enabled the defenders to drop stones and other trifles on to the heads of assailants one hundred twenty feet below.

Two iron bands now reach around the famous stone, spanning the open space, and fastened to the wall.

The aspirant who wishes to kiss the stone, must grasp these irons, one in each hand, and hang on for dear life.

As the stone is underneath the parapet, the feat of kissing it is not easy.
