As detailed before (here and here) I did a trial dig with friends in an undated great barrow near Sjögestad church in Östergötland last September. We secured samples that allowed radiocarbon dating to the Early Viking Period (9th century) and the identification of several plant species in small hearths that had been lit on the barrow as it was being erected.
I filed the excavation report the other day, and it is now available on-line in Swedish for all to read. Check it out! If anything’s hard to understand, don’t be afraid to ask.
