Cobblestones further revealed

Removal of the concrete ramp leading to the tower's southern entrance revealed more of the characterful cobblestones which seem to form a drainage channel leading to a large surface water drain at the south west corner of the tower. Now that the heavy digger and lorries have gone from the site we should be able to expose more of this (if there is more) without risk of damage. This pavement seems to be at about the right level to be incorporated into the site plan.
