This document discusses the Sensing the Iron Age and Roman Past in Hertfordshire Project, which aimed to train community archaeologists in geophysical surveying techniques like magnetometry. The project partnered with various archaeological societies to survey several Iron Age and Roman sites in Hertfordshire, including Verulamium. Some key successes were the popular training course, effective surveys that added to knowledge of sites, and collaboration between groups. Ongoing goals include publishing survey results and conducting more site work. Challenges involve resources for precise georeferencing and logistics of multi-site surveys.
