A common question relates to the structure numbers – how they are allocated and what do they represent?
The answer is quite simple.
The numbers indicate the order in which the buildings were encountered. So the first discovered on site, back in 2003, was Structure One and the most recent, from 2024, was Structure Forty-One – an earlier building beneath Structure Five.
On saying that, some of the numbers are allocated during the post-excavation process when enough evidence points to a previously-excavated feature, or features, as representing individual structures.
