This burial in Pembrokeshire is the first such discovered in Wales. Mike Smith was using metal detection equipment when he discovered the chariot. Smith, beginning in February, discovered several pieces of Iron Age Celtic metalwork, including parts of a horse harness, bronze bridle fittings, and a brooch. Several of the items still had bright red enamel. After Smith informed the National Museum of Wales of his find, the Museum and Dyfed Archaeological Trust began an excavation in June. The discovery of two iron (and rusted) chariot wheels confirmed that the site was a ritual chariot burial. These burials, which typically include the chariot, the fittings, the driver, sometimes the horses, and various necessities for life in the next world, were reserved for aristocratic burials.
