Once cleared, the flags of the walkway around the battlements are in remarkably good condition, as are most of the battlements themselves, though, in places, they are only held vertical by the grass roots which bind them. When it comes to restoration, each of these loose stones will have to be removed, cleaned, and replaced in exactly the same place.
The most fragile of the structures is the front wall of the north range, the top of which seems to have been invaded by the most vegetation, including several small shrubs and ivy. John-Paul Ashley, who was my guide and minder while I gingerly explored the walkway, advised me that it was the one section which should not be visited.
From the battlements the whole of the courtyard is laid out below. This view looks across to the east range, the most recent of the interior buildings. Now that - to put it in John-Paul's words - there is a steel ramp and 'drawbridge' at the castle's front entrance, it's been possible to get a small machine into the courtyard to help remove the material that is dropped down from the battlements.
Some of the permanent residents of the castle are none too pleased with all the activity. Not that a few builders, engineers, architects, archaeologists, rope access technicians and a stray blogger is going to prevent them from feeding their young.
Many thanks to John-Paul for a fascinating guided tour.
Well done to the starlings for hanging on in there, our wildlife is more resilient than most, be kind to them guys.
