York Historic Environment Record

The work consisted of pre-intervention Level 1 photographic recording of an area of undercroft host to a new pump sump, followed by archaeological monitoring during its excavation. The excavation of a cable trench adjacent to the western boundary wall and gatehouse was also undertaken. The excavation of the pump sumpidentified a clean reddish-brown, possibly riverborne, sand beneath the current brick floor surface. The excavation of the cable trench identified a deep, dry topsoil overlying a layer of overburden containing occasional fragments of ceramic building material and early modern pottery which was recorded but not retained. No significant archaeological remains were encountered.
