In November 2016, Ian Milsted (the Head of YAT’s York based field team) presented a Lunchtime Lecture that delved into the landscape around Skeffling in East Yorkshire, and the fieldwork that was about to happen there. After the initial phase of fieldwork was completed in late 2016 the team returned to Skeffling in 2018 and through further fieldwork found a complex landscape shaped by 12,000 years of natural action and human activity, starting from when the area was a post-glacial inland river valley up to the period it became a major coastal estuary. The 2018 work was overseen by Clare Jackson and Clare’s talk will focus on the archaeology of the Roman to medieval periods that was uncovered during this work; archaeology that undoubtedly reflects the important land-use changes in this most fluid of landscapes.
