Dendrochronological synchronisms between the dated log and other timbers provide annual precision for the construction of the site. The felling date obtained, AD 835, is 50–60 years later than that proposed previously (Meadows and Zunde 2014) on the basis of a wiggle-match between 14C ages of decadal blocks and the IntCal13 calibration curve (Reimer et al. 2013), although the same 14C data favor a felling date in the AD 830s when wiggle-matched to IntCal20 (Reimer et al. 2020). Our results appear to confirm doubts expressed by Philippsen et al. (2022) about IntCal20 values from ca. AD 825-835. 4950 https://doi.org/10.1017/RDC.2023.24$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8:3-2025-00044-8$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/macau_mods_00005565 5051 530 5051 930 5550 IntCal13 5550 IntCal20 5550 Miyake event 5550 single-year sampling 5550 wiggle-match
