The 3D computer model showing the radar survey results from the west end of the chapel

The image shows a 3D projection of the survey results as if looking into the ground from the south-west corner of the building. The main feature displayed is the 'vault-like' anomaly, perhaps collapsed at its west end and with a passage-like feature extending towards the east. The apparent vertical wall at the east end of the image is an anomaly of the computer model and not a real feature.
