Phase two of the conservation project involves capping the top of the Keep walls with turf to protect them from further weathering; repairing original plasterwork; pinning back loose sections of stonework, and re-bedding and re-pointing various sections of the walls. This has necessitated building a 23-metre scaffolding tower to scale the tall thin pillar of the East Wall of the Keep. A 30-metre stairway from the Outer Bailey to the Keep provides access for the conservation team. Alongside is a ‘railway track’ which transports equipment and scaffolding poles up the steep embankment - Link .
