The Ancient Monuments Society has also raised concerns about the plans, saying it does not believe there is “sufficient information at this stage to discharge this condition”.
The group said: “This part of the site is clearly of great historic and archaeological interest, yet no information has been submitted with the application regarding the changed and additional archaeological or heritage impacts to justify this particular proposal.
“This is a concern given the extent of demolition, excavation and alterations required to the theatre wall, and area between the theatre and town walls, to facilitate the network of ramps as proposal.”
Colchester Council officers are set to rule on the plan.
