A granted aided project to construct a timber walkway access to the inner bailey of Bungay Castle would involve limited invasive groundworks, particularly associated with the removal of 20th century concrete garden features. In order to ensure that no archaeological deposits were damaged during the construction process, the removal of the six areas of concrete was undertaken by archaeologists. All of the concrete was found to be superficial in character, only set into the topsoil layer.
In addition, English Heritage asked for a trench to be manually excavated across the projected line of the extant inner bailey wall where it crossed the proposed walkway. No evidence was revealed to suggest that the wall had continued at this juncture, with topsoil recorded lying directly on orange sand and gravel subsoil.
