CORNWALL, ENGLAND—The Cornwall Archaeological Unit and English Heritage have unearthed thick stone walls that may date to the sixth century in previously unexcavated terrace areas near the thirteenth-century site of Tintagel Castle. Geophysical surveys of this area suggested that two rooms sit below the surface. The excavation team has also recovered fragments of imported pottery and glass, suggesting that the sixth-century residents of the site were wealthy. Among their belongings, archaeologists have found late Roman amphoras and fine red-slip tableware imported from western Turkey. “The discovery of high-status buildings—potentially a royal palace complex—at Tintagel is transforming our understanding of the site,” Win Scutt of English Heritage told The Telegraph.
