Excavations by MoLAS at 30 Gresham Street and 12 Arthur Street in the City of London in 2001 have led to a complete reassessment of the provision of Roman London’s water supply. Four massive first- and second-century wells contained remains of two types of mechanical water-lifting machines or bucket-chain systems. The discoveries allowed identification of a similar bucket-chain from the Cheapside Roman baths, found 50 years earlier by Ivor Noël Hume of the Guildhall Museum. Archaeological and engineering analysis has revealed the water-lifting capacity of the machines, which could have supplied a significant proportion of the town’s population with clean water.

This paper examines the significance of seventeen later Bronze Age wells found during construction at Swalecliffe, in north-east Kent. The unusual depth of the features made for exceptional preservation of wooden structural elements, including steps and revetments, demonstrating rare evidence for woodworking and woodmanship. Extensive biological remains facilitated environmental reconstruction, and a lengthy dendrochronological sequence corroborates the internationally important Flag Fen chronology. Dendrochronological and radiocarbon dates demonstrate around 500 years of seemingly continuous use and replacement of wells. Votive deposits and apparatus used for water collection provide glimpses of small-scale ritual and domestic activities. The highly unusual concentration of wells is compared to contemporary sites regionally and elsewhere.
