CAERNARFON, WALES—Archaeologists in northern Wales have unearthed the remains of a small medieval castle, reports the North Wales Chronicle. A team lead by Jane Kenny of the Gwynedd Archaeological Trust spent two years working at the site, known as Han Gastell, which had previously been supposed to be an Iron Age hillfort. But instead of prehistoric fortifications, the team discovered the remains of a defended enclosure dating to the eleventh and twelfth centuries. Kenney speculates that it was probably built by a minor noble and then occupied by no more than four generations before being abandoned. Post holes at the site indicated that the castle once had a large timber hall or tower and the discovery of a large amount of metal slag showed it had its own blacksmithy. The team also discovered decorative bronze and brass objects as well as an iron knife. To read more about archaeology in the area, go to “Letter From Wales: Hillforts of the Iron Age.”
