A nail or pin has been driven into the northwest face of this stone at an unknown point in the past. Its position is indicated below.
This is a close up view of the nail/pin.
On the southern edge of Stone 52 there is an interesting graffito: "I WREN" which is reputed to be that of Christopher Wren, a local lad who went on to design St Paul's Cathedral. The "I" has a bar through it, supposedly representing his first name. Curiously, there is a second occurrence of the name "WREN" at the monument, carved into the west face of Stone 23.
