York Historic Environment Record

Between the 20th and the 22nd September 2021 York Archaeological Trust conducted an archaeological watching brief on a sewer repair in Walmgate. The work was undertaken for Yorkshire Water in response to an Operations Notice due to the site's location within the York City Centre area of Archaeological Importance. The works involved the monitoring and recording of repairs to a sewer trench 3.4m x 2.8m in area and 2.4m deep. The earliest observed deposits were highly organic and date to the Anglo-Scandinavian period. These included the remains of a timber structure dated by dendrochronology to AD 958-981, which is a rare find. The Anglo-Scandinavian deposits were sealed by a sequence of modern deposits.
