Medieval Haywharf to 20Th-Century Brewery Excavations at Watermark Place, City of London - MOLA Archaeology Studies Series

Archaeological excavation by MOLA at Watermark Place in the City of London revealed evidence for the development of the city waterfront from the 13th century onwards. The remains of substantial and well-preserved timber river walls and timber/stone dock walls were recorded, and the use of tree-ring dating enabled the construction of one large timber river wall and dock to be dated to the year 1339. Many of the recorded structures related to the medieval wharf known as the Haywharf, probably originally so-named because it was where hay was imported into the city before c 1300. In common with other excavations of medieval waterfronts in the City, the waterlogged deposits associated with the structural remains produced a remarkable array of finds, including over 700 accessioned finds. Large medieval foundations on the site probably relate to the mansion known as Coldharbour, which was constructed on the site by the early 14th century. Later remains included a sequence of 15th- to 16th-century industrial stone hearths or furnaces, and documentary evidence suggests that it is likely these were associated with either brewing or dyeing on the site. Also recorded were structures associated with the Calvert's/City of London brewery, which stood on the site from the 18th century until it was bombed during World War II.
