York Historic Environment Record

The borehole evaluation encountered an extensive sequence of archaeology extending to depths close to 8m Below Ground Level (BGL). From approximately 4m BGL water logging has provided ideal conditions for the preservation of organic material for deposits dating to the Roman period. From the top of Roman deposits, at around 4m BGL and extending to approximately 2m BGL, a range of features and deposits potentially dating from the post-Roman through to the medieval period was observed. Intrusive medieval features, such as pits, were observed cutting down through earlier levels of deposition to depths close to 6m BGL, which raises the likelihood that environmental evidence from this period has also been well preserved. Post-medieval activity was identified from 2.5m BGL to close to 1.5m BGL. It included evidence for structures and the accumulation of garden type soils. Lastly a thick layer of modern makeup and levelling has above it the existing car park surface.
