Excavated by Leslie Alcock in the 1950s, the inland promontory fort of Dinas Powys is widely cited as a type site for elite settlements of post-Roman western Britain. Alcock's interpretation and dating of the main defences as a Norman-period castle were effectively disproven in the 1990s, but the excavator's original chronology continues to be cited. Here, the authors present a revised chronology, integrating new radiocarbon dates and stratigraphic analysis to re-evaluate the history of occupation. The new phasing redates the main defences to the early medieval period, which aligns with the site's notable early medieval assemblage. The findings contribute to understanding of post-Roman western Britain and the (re)occupation of late antique hilltop sites more generally.
