Apothecaries Hall, 10-18 Blackfriars Lane, City of London: tree-ring analysis of pine timbers from the Hall roof

Four large pine timbers from the roof over the Hall were sampled. Three of the derived ring-width sequences matched each other and were dated, the fourth timber gave a long sequence that was not dated. The resulting site sequence dated to the period AD 1382– 1666. It seems likely that the timbers were derived from a Scandinavian source, and that all three were felled at about the same time, probably in the late-seventeenth century. The roof is known to have been lost in the Great Fire of AD 1666, and there are records of rebuilding having been completed by AD 1672, suggesting that the timbers are from this phase.
