The Ruthin Dendrochronology Project which was funded by the UK Community Renewal Fund/Denbighshire Community Action Project: Approval Reference: P03 and organised by the Dyffryn Clwyd Historic Buildings Group (DCHBG). The project was organised by Helen Williams, the Community Enterprise Officer at Cadwyn Clwyd (Rural Development Agency), and Fiona Gale, Gareth Evans and Heather Williams of the DCHBG. The building interpretation was undertaken by Ross Cook (www.archaeodomus.co.uk). A total of 27 buildings were examined. Seven buildings: were rejected for sampling. Three buildings appeared to have good dendrochronological potential, but sampling was not undertaken. Seventeen buildings were considered to have reasonable dendrochronological potential and were sampled, but two Tr Wynnstay (SJ 1252 5819) and 5 Castle Street (SJ 1237 5821) failed to date. A. K. Moir, 2022, ‘Dendrochronological analysis of oak timbers from fifteen buildings in Ruthin, Denbighshire, Wales’, TRS Report LLRA/23/22.
Measured tree-ring series from 68 timbers sampled from these fifteen buildings have been used to form a 336-year site chronology called RUTHIN-18, which spans 1399 to 1734. The mean chronology RUTHN-18 is presented below:
