CenTex kev,
How did you manage to get to the terrace and look through the windows? I was there last month and the mesh fence across the south front was still in place and I did not see any gaps. I would have liked to have taken photos close up in that area. The only way I could take mine was from the steps that lead out to the Terrace from the Semi-circular Hall but I was not allowed to stand on the Terrace only on the step in the doorway leading to it.
