Alice Roberts tours three archaeological sites in the north of Britain, with footage shot on location by the excavating archaeologists themselves. At Vindolanda, a Roman fort near Hadrian's Wall, she examines writing tablets, swords, and household objects left behind during a period of British rebellion, the wooden tablets preserved so well that ink handwriting is still legible. On Iona, off the Scottish coast, diggers uncover traces of a monastery and pilgrimage route founded by Saint Columba, a site some scholars have compared in significance to Jerusalem. In eastern Scotland, a weapons hoard belonging to a Bronze Age warrior comes out of the ground, offering clues about wealth and status centuries before Rome ever reached Britain. Roberts moves between trenches and finds tables, letting the archaeologists explain what each object tells them in the moment of discovery rather than reconstructing conclusions after the fact. The result is a hands-on look at how three very different periods of British history, Roman, early medieval, and Bronze Age, get pieced together from what survives in the soil.
