The report on the recent investigations, and the antiquarian study, at Aldborough is out soon!
In 2009, a team of archaeologists led by Dr Rose Ferraby and Professor Martin Millett began a major re-examination of the site. Large-scale geophysical surveys using both gradiometry and high-resolution ground-penetrating radar were conducted and these revealed most of the town and its surroundings, allowing its development from the second century AD to the medieval period to be mapped with great accuracy.
