CARDIFF, WALES—In advance of restoration of the western moat at Cardiff Castle, archaeologists carried out excavations of the former defensive watercourse, also known as Mill Leat. The team recovered some 3,000 artifacts, mostly from the 16th and 17th centuries, including a pewter spoon and Venetian glass that would have belonged to individuals of high status. The moat also once served as a millpond that supplied water to corn mills outside the castle, which was originally built by Norman invaders in the 11th century. The moat has now been reflooded to return it to its medieval appearance.
